Any comments ?

Is it a bug or the concept of overlay scrollbar ?

Pretty sure it's a bug. Overlay scrollbars are supposed to overlay the content in their scrollable area, NOT content in a totally different element which is above it in z.

I am not able to reproduce this bug in Safari 16.5 and it does not show 'scrollbar' on top of Green Rect like reference image.

Chrome Canary 116 and Firefox Nightly 116 are matching Safari as well.

This is fixed now.
