Description Chris Lord 2021-05-18 09:42:11 PDT 
These spatial navigation tests fail since enabling async overflow scrolling in tests in WPE:

fast/spatial-navigation/snav-clipped-overflowed-content.html
fast/spatial-navigation/snav-only-clipped-overflow-content.html
fast/spatial-navigation/snav-simple-content-overflow.html

Debugging with alexg, we discovered that this was because of clipping being disabled when async compositing is used at the RenderBox level. This leads us to believe that this issue may not be WPE-specific. Patch incoming.

Patch

I would prefer this happen in two stages: the first should just bet the clippedOverflowRect changes, and the second, smaller patch would fix spatial navigation.
