As a result, items in the same alignment context can be in the same baseline sharing group is their baseline alignment preferences are compatible https://drafts.csswg.org/css-align-3/#baseline-terms 1975989 1 webkit-bug-importer 2023-09-06 17:01:42 -0700 <rdar://problem/115083708> 1975993 2 sgill26 2023-09-06 17:17:31 -0700 Pull request: https://github.com/WebKit/WebKit/pull/17517 1977152 3 ews-feeder 2023-09-12 15:13:30 -0700 Committed 267922@main (caab01d5e748): <https://commits.webkit.org/267922@main> Reviewed commits have been landed.
