Automatic update from web-platform-tests [CompositeScrollAfterPaint] Consider composited scrolls in CanUpcastWith In CompositeScrollAfterPaint, the compositing status of a transform node not only from HasDirectlyCompositedReasons(), but also composited scroll status determined by PaintArtifactCompositor. This requires PropertyTreeState::CanUpcastWith also check composited scroll status when checking if two transform nodes are within the same compositing boundary. Also PaintArtifactCompositor needs to handle a case where a scroll translation is used before the ScrollHitTest chunk. This happens for negative z-order scrolling contents in a non-stacking-context scroller. In the case we always composite the scroller to prefer performance because it's likely there are overlapping interlacing scrolling and non-scrolling contents. This can also simplify code because otherwise we would need to find the ScrollHitTest and compute composited scroll status.
