Hi Team,

While going through Blink's commit, I came across another potential failing test case in Safari 16.2 & STP161:

Test Case - https://jsfiddle.net/3c79t0ge/show

^ Does not scroll and does not show scrollbar. Works fine in Chrome Canary 111 and Firefox Nightly 111

Blink Commit - https://chromium.googlesource.com/chromium/blink/+/d050f9be579d02e40c8924b4153376bc32ffba1a

WebKit Source - https://searchfox.org/wubkat/source/Source/WebCore/rendering/RenderOverflow.h#76

Just wanted to raise it so we can fix it.

Thanks!
