Setting tracking label Blimp-M54-Proj-Scope.  This label is for scope tracking purposes only and should not be added / removed from any bugs, even if we add additional bugs to M-54 scope, or remove this bug from M-54 scope.

Now this blocks  issue 653371  for LayerTreeHostTestSurfaceDamage in remote mode. This test verifies that subtree property changes are verified correctly in RenderSurface::AncestorPropertyChanged. And since we re-sync the hierarchy with the client for every frame, for the compositor on the client, each frame comes with the subtree changed for each layer.

Obsolete, WontFix.
