RenderLayerBacking::updateInternalHierarchy() is called in some instances where there doesn't need to be a complete reparenting of the the m_graphicsLayer. For example, on OS X when the user changes the scrollbar styles to/from always visible. We don't need to always remove the graphics layer from its parent - any reparenting does that automatically. Unfortunately we can't trigger this situation in an automated test. <rdar://problem/14290395>
