Automatic update from web-platform-tests [css-layout-api] Baselines This change adds support for the CSS Layout API Alignment, both in retrieving child baselines and in setting parent baselines. https://drafts.css-houdini.org/css-layout-api/#interaction-alignment Due to recent changes, fragments produce only one baseline. https://chromium-review.googlesource.com/c/chromium/src/+/1988376 As a result, custom LayoutFragments will always produce the first-line baseline.
