Hi Team, While going through Blink commits, I came across following commit: Link - https://chromium.googlesource.com/chromium/blink/+/ed902d339fbff3a62e2f6124d8d40bbad45e97c0 Which removed a hacky optimization added in 2006. We still have this optimization here: https://github.com/WebKit/WebKit/blob/fa2a14f12031baf24d5bc6d6727c3e25c5052589/Source/WebCore/rendering/RenderBox.cpp#LL2610 The testcase attached render same as Chrome Canary 109 as in Safari Technology Preview 157 and Safari 16.1: Test Case - https://jsfiddle.net/m4hja1pv/show But I think it would be better tested in EWS. I will tag @Alexey (ap), who landed this in 2006. Just to get his input. Thanks!
