This might be a stupid question, but... In the case where paintParent is null, shouldn't we still setDescendantsNeedUpdateBackingAndHierarchyTraversal() on ourselves? auto* layer = paintOrderParent() ? paintOrderParent() : this; layer->setDescendantsNeedUpdateBackingAndHierarchyTraversal();

I believe that case is impossible and that if() is just being overly defensive.

paintOrderParent() is only null for RenderView, so that should never hit this code.
