Hi Team,

While going through Blink's commit, I came across another early return potential optimization, which I think would be good to add to WebKit.

Blink Commit - https://chromium.googlesource.com/chromium/blink/+/1add5ffe5081cf282014bc4cfe04b8637244c607

WebKit Source - https://searchfox.org/wubkat/source/Source/WebCore/rendering/RenderLayerScrollableArea.cpp#1750

___

It compiles locally with following:

if (!m_resizer && !m_layer.canResize())
return;

___

Just wanted to raise this bug for input and if this can also give optimization to WebKit then I can do PR.

Thanks!
