Summary RenderLayer::collectLayers uses compositing state which isn't valid yet
Matt Woodrow
Reported 2024-07-10 15:01:02 PDT
RenderLayer::collectLayers decides whether to include layers inside visibility:hidden based on `compositor().usesCompositing()`, which isn't (guaranteed to be) computed until after compositing layers have been decided. If the compositing state does change, nothing invalidates the RenderLayer z-order lists, so we can remain in this unexpected state.
