Updates since last meeting (on Monday, August 10th):
Scrolling (skobes, szager) [crbug.com/
- Moved scrolled-by-user flag out of FrameView. (skobes)
- Custom scrollbars are now working with root layer scrolling. (skobes)
CSS Flexbox (cbiesinger) [crbug.com/
426898 ] - Got go-ahead to unprefix intrinsic sizing keywords (min-content, max-content, fill and, fit-content). Will go ahead and unprefix all but fill (currently -webkit-fill-available) as there is still some open questions around it and the CSS working group doesn't quite think it's ready for prime time yet.
- Added use counter for prefixed intrinsic size keywords.
CSS Grid Layout (svillar) [crbug.com/
79180 ] - Working on refactoring min/
max ContentForChild calls to share more code and logic. Region-based multi-column support (mstensho) [crbug.com/ 334335 ] - Landed initial support for nested multicol layout. Column balancing still needs work but the most common use cases work.
- Plan to hook up printing code once I'm more confident about the
implementation. Will finally enable multicol for printing for the
first time ever in Blink. :) (mstensho)
Add API for layout (leviw, pilgrim, ojan)
[crbug.com/
495288 ] - Landed several API patches and finishing up API conversion for box model object. Estimate about a weeks worth of work remains. (pilgrim) Text (eae, drott, kojii)
- Debugging font matching issue on windows, looks like Skia is not returning the full font name. (drott)
- Implemented tab characters for complex path, one of the blockers to unify simple path to complex path. (kojii)
- Landed font fallback cleanup to fix a crash bug with support from the memory team. (kojii)
- Enabled Unicode Variation Selector for Chrome OS. (kojii)
- Eliminated the last remaining direct caller to HarfBuzzShaper for better layering. (kojii)
- Fixed handling of invalid and unmatched UTF-16 surrogate pairs, we now replace invalid pairs with a replacement glyph and keep processing the rest of the text node while before we would abort after the first invalid character and not paint the remaining text. (eae)
- Fixed handling of tabs in complex path in cases where tabs are not supported. (eae) Misc:
- Cleaned up PageBoundaryRule and nextPageLogicalTop. (mstensho)
- Fixed issue with auto-height table cells and percentage heights that broke a couple of popular legacy websites. (mstensho)
- Issue with win10 bots where hundreds of tests where failing and tools not yet updated to support win8 or win10 specific results, since resolved. (cbiesinger)
- Got go-ahead to upstream layout tests to W3C. (cbiesinger)
- Discussion around layout test standards and guidelines, jsbell gave update on plan to support web platform tests and will send out further information when ready.
- Wrapping up custom properties. (leviw) Logistics:
- cbiesinger gardening last week (Thu-Fri).
- leviw gardening this week (Mon-Tue).
- Pre-CSS F2F meeting in SF on Tuesday.
