- The polls run on twitter for the name change in issue #7317 (Rename Element.isVisible to Element.isHidden?) produced reasons against both names. checkVisibility was also suggested and had mixed support. Bikeshedding will continue on github to collect ideas.
- The concerns about a previous resolution explained in issue #7066 (Revisit decision to make ‘style’ the default ‘container-type’) were around both author clarity and performance issues in some cases. Most of the group’s focus was on ensuring that the property works well for the authors. There was a new proposal to use longhands that needs to be discussed more as a potential solution before the group tries to reach a resolution.
- Resolved: Keep ‘distribute’ keyword alias (Issue #7322: Consider removing distribute value for text-justify from the spec)
- Resolved: text-align: match-parent computes to ‘start’ on the root element (Issue #6542: text-align: match-parent on the root element with direction: rtl doesn’t match browsers)

- Future meeting timing:
- The deadline for TPAC meeting requests is the end of May. Please send any preferences for meeting days to the private list.
- Next week there will be an extended meeting to cover the Selectors topics.
- There have been some suggestions to have a hybrid in person/remote session over the summer. If there is interest please reach out to the private list.
- iank introduced the concept of CSS Anchor Positioning to allow positioning elements relative to other elements in the DOM. There were some initial questions and positive feedback. Discussion will continue on the private github until the proposal is formally moved into the working group’s scope. Any substantial changes will also be noted in github issue #7282 (Introduce CSS Anchor Positioning).
- More examples will be added of the current unexpected behavior mentioned in issue #7251 (Composition of inset shadows). astearns will also do research into if there is already examples we can follow in the Adobe products.
- Resolved: Leave text-shadow spread details undefined right now, with possibility of specification later after impl experience (Issue #7250: Text shadow spread corners)
- Resolved: No change (Issue #7249: Make U+0000 invisible?)
- Bugs will be filed with the browsers to see if they are willing to align to the spec on issue #6542 (text-align: match-parent on the root element with direction: rtl doesn’t match browsers). If the browsers have specific reasons to not conform to the spec the group will consider changing the spec.
- The features listed in issue #7310 (Are these features ready to ship?) are not ready to ship yet, but there is interest in prioritizing them to become ready to ship.

- Resolved: Remove checkInert from IsVisibleOptions (Issue #7274: isVisible inert option)
- There were some concerns about the proposed new keyword for font-display (Issue #7271: Add a font-display keyword to eliminate @font-face FOIT & layout shifts) encouraging authors toward behavior that is bad for users. Discussion will go back to github to discuss further the intent to assist authors in making a decision they’re already trying to make and how to balance that against the concerns.
- Resolved: forced-color-adjust doesn’t do anything on highlight pseudos, and highlight pseudos take their forced color state from the originating element (Issue #7264: Highlight pseudos and forced-color-adjust)
- Resolved: Issue of topmost modal dialog to be addressed with a pseudo-class (name TBD) (Issue #7258: Should :active apply to dialogs?)
- Resolved: Add :-webkit-autofill in an appendix of selectors 4 (Issue #7257: List of -webkit- legacy aliases)

- Resolved: thin, medium, and thick will be defined as 1px, 3px, and 5px respectively. (Issue #7254: Specify exact pixel values for border-width: thin, medium, thick)
- More research needs to be done on current behavior and complexity to change implementations prior to reaching a decision on issue 7164 (How to handle linked list-valued properties?)
- Resolved: Always require inline-end padding to be added against the inline-end alignment edge for block/flow layout when it’s a scroll container, thus matching the tests. (Issue #129: Clarify padding in overflow content)
- Resolved: Accept the proposed PR. (Issue #7101: Highlight pseudos and emphasis/underline properties)
- More testing is required around filter and backdrop-filter to determine a resolution for issue #455 (backdrop-filter and visibility)
- The Safari and Blink teams need to investigate the web compat of solving issue #7227 (counter-reset in UA sheet causing some compat issues) without magic

Updated WD of Selectors Level 4
The CSS Working Group has published an updated Working Draft of Selectors Level 4. Selectors are patterns that match against elements in a tree, and are used most famously in CSS style rules as well as various Web platform APIs.
This long overdue update adds quite a few new pseudo-classes: :defined, :modal, :fullscreen, :picture-in-picture, :muted, :volume-locked, :seeking, :buffering, :stalled, :autofill, and :user-valid. It also adjusts parsing rules for most pseudo-classes such as :is() that accept selectors (but not :not()) to ignore invalid selectors in their arguments, preventing these from invalidating the entire selector. Changes since the last Working Draft are listed in the Changes section.
Please send feedback by either filing an issue in GitHub (preferable) or sending mail to the (archived) public mailing list www-style@w3.org with the spec code ([selectors-4]) and your comment topic in the subject line. (Alternatively, you can email one of the editors and ask them to forward your comment.)
CSS Text Decoration L4 Update
The CSS Working Group has published an updated Working Draft of CSS Text Decoration Level 4. This module contains the features of CSS relating to text decoration, such as underlines, text shadows, and emphasis marks.
Updates in this draft include:
- Adding spread distance to
text-shadow
- Adding
inset to text-shadow
- Clarifying application of
text-decoration-skip-ink
Further planned work on this module includes:
Please send feedback by either filing an issue in GitHub (preferable) or sending mail to the (archived) public mailing list www-style@w3.org with the spec code ([css-text-decor-4]) and your comment topic in the subject line.

- Resolved: Republish Will Change 1 as CRD (Issue #7177: Republish)
- Resolved: Add CanvasFilter to PaintRenderingContext2D (Houdini Issue #1056: Add CanvasFilters to PaintRenderingContext2D)
- Resolved: Remove
1d-image from image for now, open a separate issue to discuss it (Issue #2532: Issues with listifying border-color)
- Resolved: NaN escaping calc() tree is coerced to zero (Issue #7067: Make top-level NaN be invalid at computed value time instead of ∞)
- There was discussion around what would be referenced by the proposed :modal pseudo-class (Issue #6965: Add :modal-dialog pseudo-class). If it’s things appearing on the top of the page, :top-layer may be a more appropriate name. Concern was expressed about if the :modal name was going to be too broad for an initial pseudo-class and if the property should start specific and then create a generic as more use cases develop. Alternatively, a broader name would allow clearer combination with other pseudo-classes and future extension without creating a lot of pseudo-classes. Discussion will continue on github and the group will continue to engage with the OpenUI group on this topic.

- Resolved: Accept Florian’s pr and submit the corresponding one to HTML (PR #7224: Provide hooks for HTML to define rendering for widgets)
- Resolved: Reverse previous resolution. Add a unit instead, name tbd (Issue #3232: Syntax for percentage-of-width-of-space for ‘word-spacing’)
- Resolved: Have preferred-color-scheme reflect ‘color-scheme’ on the embedding element in the embedding document, to the extent acceptable from security standpoint (pending security review) (Issue #7213: Should prefers-color-scheme in SVG images be context-dependent?)
- Resolved: Force iframe/object/embed/any other scriptable document-embedding element to object-overflow: clip !important; via UA rule (Issue #7143: object-* properties and the iframe element)
- Chromium and Gecko will investigate their filter color space to see if the proposed solution for issue #7100 (Should no-op filters produce different output from no filter?) will be okay.
- Resolved: System colors compute to absolute colors, but must not be affected by forced-colors mode (Issue #6773: Make system colors fully resolve (but flag they were system colors) thus reversing the resolution of #3847)
- Resolved: Republish css-color-4 and css-color-5
- As the call was concluding, there was consensus building to have NaN become 0 instead of ∞. Discussion will continue on issue #7067 (Make top-level NaN be invalid at computed value time instead of ∞) and then come back to the group for resolution.

- Pull request #6537 (Define how to compute the kind of widget to use for an element) will be merged next week unless there are edits to it before then.
- Resolved: Highlight pseudos continue to inherit the text-decor properties, but do not propagate decorations the normal document. (Issue #6829: highlights and decoration propagation)
- Resolved: Add .layerName to CSSStyleSheet as a readonly attribute. (Issue #7002: Add a .layer attribute to CSSStyleSheet)

- Resolved: Require the container name in the shorthand syntax (Issue #7142: container :/ size)
- Resolved: ‘none’ does not compute to ‘normal’ (Issue #6503: Implementing content:none on elements is not web-compatible)
- Resolved: Add this path forward to the spec with a note linking back to this issue (Issue #7144: How do object-overflow and object-view-box interact with overflow and overflow-clip-margin?)
- The spec text written for the above resolution will need to add details for handling of overflow-x and overflow-y
- A use counter will be added to track the current usage of overflow:visible on replaced elements. If the use counter comes back with data this might be a breaking change the group will revert the above resolution and go back to exploring a separate property to have this behavior.
- Resolved: Add a URL parameter-specific version of image-set function to the cursor property (Issue #5831: Should the cursor property support image-set()?)
- Resolved: Close no change (Issue #7083: Should ‘revert’ really treat animation origin as author origin?)
- Resolved: Specify what browsers currently do (Issue #7054: revert/revert-layer with logical properties)
