Updates since last meeting (on Monday, January 25th): Scrolling (skobes, szager) [crbug.com/417782]
- Prototyping scroll anchoring and added a flag for enabling it, --enable-scroll-anchoring. Working on a basic implementation. Current design looks solid and well encapsulated. Still needs testing in the real world but looks promising. (skobes)
- Changed LayoutRoots to avoid making scrollbars trigger relayout. (leviw) CSS Flexbox (cbiesinger) [crbug.com/426898]
- Fixed a number of flexbox regressions last week. As of now all known regressions in 49 and 50 have been resolved. Most 48 regression have been addressed, merged a last fix this morning.
- Flexbox interop work continues, including a follow up to a temporary fix for a regression. CSS Grid Layout (svillar, jfernandez, rego, javif) [crbug.com/79180]
- No update since last meeting. CSS Multi-column (mstensho) [crbug.com/334335]
- Intent to unprefix multicol as is turned out not to be too popular. Gated on generic breaking properties. Will send out a separate intent for that. Breaking properties are generic and apply to all paginated (and in theory region based) content. Not simply an alias for -webkit prefixed properties as the values differ.
- Fixed a number of multi-col bugs. CSS Houdini (ikilpatrick)
- Presented custom paint, custom properties and custom layout at CSS working group meeitng in Sydney. (ikilpatrick)
- Updated custom paint, custom properties and custom layout specifications. (ikilpatrick)
- Barista for the houdini working group, exceeding expectations. (ikilpatrick) Add API for layout (leviw, pilgrim, ojan) [crbug.com/495288]
- Moved resolvedColor to use line layout api, had a lot of cascading effects that allows for simplifications in TextPainter and further allows the API to be used in unit tests. Nice properties and simplification ensued. (pilgrim)
- Multiple line layout patches includes a potential large change to the API that was discussed last week. Fully up to speed on api work and have a few layout patches pending. (dgrogan) CSS Containment (leviw) [crbug.com/312978]
- Discussed CSS containment at CSS working group meeting, positive signals from working group and other implementors. (leviw) Intersection Observer (szager, mpb) [crbug.com/540528]
- Added optimization to skip render-throttled iframes during hit testing. (szager) Text (eae, drott, kojii)
- Presented CSS Writing Modes, CSS Text Decorations, and Snap at CSS Working Group meeting in Sydney. (kojii)
- Emoji segmentation, tests on all platforms. Some blockers on Android due to lack of capabilities with regard to font family based font selection for fallback. (drott)
- Enabling open type features through CSS keywords. (kojii)
- Dealing with regressions and fallout following font fallback overhaul. (drott) HTML Tables (dgrogan)
- Misc table interop fixes relating to percentage height resolution. (dgrogan)
