<pre>Actually GraphicsLayerCA::setVisibleAndCoverageRects() copies the m_intersectsCoverageRect flag to the mask layer.
The bug happens when GraphicsLayerCA::setVisibleAndCoverageRects() is called for the masked layer before it has a mask. After than, assigning the mask doesn't ever update the mask's m_intersectsCoverageRect.</pre>
