Bug 279325 – ScrollRectToVisible should bubble up through its layout container

• Status: NEW
• Component: Scrolling

[Ahmad Saleem]

Hi Team,

While going through Blink's scrolling test cases, I came across another failing test case in Safari.

Test Case: https://jsfiddle.net/Lo6nay95/

^ Fails in Safari Technology Preview 202 & WebKit ToT while passes in both Chrome Canary 130 and Firefox Nightly 132.

Blink Commit: https://source.chromium.org/chromium/chromium/src/+/57da1c75484e5a3f0af03d038c43e6f23e1549e8

WebKit Source: https://searchfox.org/wubkat/rev/b36cbce69fddb7da33823f316bd8ead5bebee970/Source/WebCore/rendering/RenderLayerScrollableArea.cpp#1959

I tried locally but it does not progress test case:

if (renderer.containingBlock())
        restrictedByLineClamp = !renderer.containingBlock()->style().lineClamp().isNone();

___

Just raising so we can track and fix it.

Thanks!
