Hi Team, While looking through Safari specific failures on WPT, I noticed that we fail following: WPT Test Case - https://wpt.fyi/results/css/CSS2/linebox/baseline-block-with-overflow-001.html?label=master&label=experimental&aligned&q=safari%3Afail WPT Test Case Live Link - https://wpt.live/css/CSS2/linebox/baseline-block-with-overflow-001.html ^ Only Safari fails and even STP237 as well. Blink Commit - https://chromium-review.googlesource.com/c/chromium/src/+/1701618 *** CSS2 defines[1] the baseline of an 'inline-block' is the bottom margin edge if its `overflow` property is other than `visible`. [1] https://drafts.csswg.org/css2/visudet.html#propdef-vertical-align *** Just raising, so we can fix it. Thanks!
