Automatic update from web-platform-tests Do not send detached scrollable area info to the compositor We track scrollable areas on LocalFrameView, and these persist even if the local frame view is detached. For PaintArtifactCompositor::Update, we should ignore the scrollable areas from detached frames, as they will not be visible.
