- Resolved: Specify outline as ink overflow (PR #9824 | Issue #8649: Specify extent of ink overflow)
- Resolved: Alignment on scroll containers results in same layout as non-scrolling containers, and doesn’t affect whether initial scroll position is zero-coordinate, just changes which direction and how far you can scroll (Issue #4957: What is supposed to happen to abspos in an end-aligned scroll container?)
- There was more discussion to be had about testing for issue #9508 (Upgrade to Recommendation?) so discussion will return to github.
- Resolved: Choosing the innermost for textbox:trim for most requested trim metric (Issue #5426: text-box-trim accumulation)
- Resolved: ink-overflow spills out of the page content area into padding and margins, user agents that can’t draw ink overflow may shift content down to avoid clipping (Issue #5335: text-box-trim vs fragmentation)
- Resolved: Should text-box-trim apply at fragmentation breaks, depend on the box-decoration-break property (Issue #5335)

Text-Focused Extra Meeting
- Resolved: Define that hanging punctuation is set to none for pre elements in the user agent style sheet (Issue #9689: Prevent `pre` from inheriting hanging-punctuation by default with a user-agent style rule)
- Resolved: Forced break resets the balancing algorithm for text-wrap:balance (Issue #9112: Should `text-wrap: balance` apply separate logic before and after forced breaks?)
- Folks requested more time to think about issue #9310 (Interaction of `text-wrap: balance` and `(-webkit-)line-clamp`), especially for creating stability when there’s a display more text option after a one line block

- Resolved: Add a keyword for alignment on blocks, with the specific name TBD (Issue #3559)
- Resolved: ‘auto’ means push or replace that’s not browser UI, or traverse with any user involvement, excluding any reloads (Issue #8783: Define navigation descriptor for @view-transition)

Extended Meeting Minutes
- Resolved: Add ‘all’ keyword to ‘timeline-scope’, equivalent to specifying all possible names (Issue #9158: Add a way for timeline-scope to pull up all contained timelines)
- Resolved: Add ‘scroll’ named range to view timelines, represents entire scroll range, bikeshed keyword in issue (Issue #9367: Range for entire scroll range)
- Resolved: Any position within the overlarge snap area is a valid snap position, as defined in the (clarified) spec (Issue #6863: Difficult to use snap areas which are larger than the scrollport)
- Resolved: fr values in stripes() convert to max(0, 100% – sum-of-percents – sum-of-fixed) * flex value / max(1, sum-of-flexes) (a ‘length-percentage’) when needed for interpolation (Issue #8622: Allow transitions between different types within `stripes()`)

- Resolved: Percents that are resolved against numbers do that at parse time (Issue #9395: Resolve `percentage` representing `number` or `angle` at parse time)
- Resolved: Drop mix() from Values 4 (Issue #9343: Abandon mix()?)
- Resolved: We will never use mix to represent a single interpolated value but may have something like it for expressing the whole interpolation (Issue #9343)
- Resolved: Specify option 7 [Join with preceding ranges if there are later overlapping ranges and the gap is short] as normative behavior (Issue #9187: Improve or clarify nested snap behaviors)
- Resolved: Specify the whole list in this order as normative behavior (Issue #9622: Standardize snap point selection with multiple aligned boxes)
- Resolved: Revert the previous resolution and the associated edits (Issue #5477: CSS counter scope/inheritance is incompatible with HTML ordinals)
- Resolved: The working group is interested in defining an opt-in narrow scope for counter resets. Exact syntax tbd (Issue #5477)
- The group wants to make sure that if we make changes in issue #8915 (Blocking effects of timeline-scope) it wouldn’t lead to problems that would make containment less impactful. Discussion will return to the issue for more investigation.
- Upcoming meetings:
- Next week there will be an extra hour of meeting to cover additional topics.
- The next F2F will be Feb 12-14 in Mountain View CA. Group members are asked to add to the wiki if they will be attending.

- Zoom will be specified in the Viewport spec
- Resolved: getComputedStyle() returns unzoomed value so that it round-trips (Issue #9398: Zoom and CSSOM)
- Resolved: APIs that return bounding boxes such as getClientRects and getBoundingClientRect and IntersectionObserver return values in page-global px unit coords (Issue #9398)
- Resolved: font-size is not special wrt zoom (Issue #9397: Zoom and inheritance)
- Resolved: All computed absolute lengths are zoomed when inheriting (Issue #9397)
- Resolved: If overflow:scroll is set on the root element (not propagated from body), account for the default scrollbar width in the size of vw. Also take scrollbar-gutter (and scrollbar-width, the property with “normal” and “thin”?) into account on the root. Ignore all of these in MQs. And also ignore all of these when using vw/vh units on the root element, if necessary (Issue #6026: Use of 100vw is causing pointless horizontal scrollbars on some websites)

- Resolved: Accept some form of masonry slack property; exact algorithm TBD; exact name TBD (Issue #9328: Reordering threshold)
- Resolved: Though it was clear how Masonry would handle `auto-repeat` accepting intrinsic sizes, it was more uncertain if it could work in Grid. Discussion will continue in issue #9321 (Allow `auto-repeat` (i.e. repeat(auto-fill|auto-fit, …)) to accept intrinsic sizes) to understand further how it could be added to Grid.
- Resolved: Restore text simplifying out single-argument min/max functions (Issue #9559: Simplification algorithm should possibly return single child for min/max)
