Hi Team, While going through WPT, came across another failing case: Blink Commit: https://chromium-review.googlesource.com/c/chromium/src/+/7836325 Test Case: http://wpt.live/compat/webkit-box-z-index.html ^ Chrome is aligning with Firefox in above commit. WPT Test Case: https://wpt.fyi/results/compat/webkit-box-z-index.html?label=master&label=experimental&q=webkit-box-z-index.html Thanks!
