Automatic update from web-platform-tests [PE] Set GraphicsLayerUpdate bits on the enclosing stacking composited layer. This ensures that we will paper over any confusions regarding non-stacking composited layers such as as those created by backface-visibility: hidden. Setting the bit on the enclosing stacking layer suffices because any other composited layer must be a stacking child of it, and the kGraphicsLayerUpdateSubtree is used.
