Hi Team,

While going through Blink's commit, I came across another where we are failing tests but Chrome Canary 113 is passing them while Firefox Nightly 112 is matching Safari Technology Preview 164.

Test case - https://jsfiddle.net/tzj4kq28/show

Blink Commit - https://chromium.googlesource.com/chromium/blink/+/ae8d18613905f501a3ce9ba83193fe77e920afbf

WebKit Source - https://searchfox.org/wubkat/source/Source/WebCore/platform/ScrollableArea.cpp#857 & https://searchfox.org/wubkat/source/Source/WebCore/platform/ScrollableArea.cpp#899

I have done local merge of this patch but it does not lead to pass on this testcase but it would be good to track and get input whether this is legit bug in WebKit or not.

Just raising for tracking.

Thanks!

I'm not sure. 
Safari and Firefox are behaving the same in these tests.
