Hi Team,
This might be partial merge of following Blink commit:
Blink Commit - https://chromium.googlesource.com/chromium/blink/+/8991628a5345bdc95e6063aac05a3d71a43ca173
I have seen at least two cases (during triaging old bugs), where we paint black bar in place of scrollbar and when we resize then we get scrollbar or the area (black) get removed.
Webkit GitHub Source - https://github.com/WebKit/WebKit/blob/403e78eb6ddb81c1319cca7045b09199474573ed/Source/WebCore/rendering/RenderLayerScrollableArea.cpp#L1476 & https://github.com/WebKit/WebKit/blob/403e78eb6ddb81c1319cca7045b09199474573ed/Source/WebCore/rendering/RenderLayerScrollableArea.cpp#L1421
Just wanted to raise this bug and get input. It does not have any dedicated test case.
If without test, it is OK to merge then I am happy to do PR.
Thanks!
