Minutes Telecon 2019-12-18
- Dates for the summer 2020 F2F will be finalized on the private list.
- Resolved: Publish a new WD of CSS UI L4
- The group discussed limiting the exposed fonts in order to limit fingerprinting vectors (Issue #4497: Limit local fonts to those selected by users in browser settings (or other browser chrome)) and was interested in creating possible spec text.
- Even though there are plenty of other vectors to fingerprint users, a majority of the group felt that it was worth the effort to chip away at the problem.
- There were different options as to what fonts to use; an intersection of OS fonts, a union of them, or somewhere in the middle where we accept that you’ll still be able to know basic information like OS from the font list.
- Though the spec shouldn’t list exact fonts, there was a desire to have an accompanying note-like document that does say fonts which are known to conform to the spec text.
- In the current GitHub there is a proposed way to still allow users to install and allow a font and that use case is important to support as this is a common need for users that consume content in a minority language.
- Though there’s a desire to ensure this text strongly protects users of browsers it may still need to be a SHOULD level requirement as there are other use cases where fingerprinting isn’t a concern such as PDF renderers
- Resolved: Reverse previous blockification requirement and require generating a block container (Issue #4448: How should spaces be treated in markers?)
- Resolved: Use white-space:pre as the value in UA stylesheet with text about possibly processing new lines (Issue #4448)
