Cherry-pick r276492. rdar://problem/77581017
Do not set synchronous scrolling for layers without relevant scrolling scopes
https://bugs.webkit.org/show_bug.cgi?id=221383
Reviewed by Simon Fraser.
Fixed backgrounds could force the layer compositor to set synchronous scrolling because they're slow
to repaint. However that cannot be done if the layer's boxScrollingScope hasn't been previously updated
in RenderLayer::updateLayerPosition.
* rendering/RenderLayerCompositor.cpp:
(WebCore::RenderLayerCompositor::updateSynchronousScrollingNodes): Do not call
setSynchronousScrollingReasons() if there is no scrollingScope.
