--- Comment #4 from Antoine Quint <graouts at webkit.org> ---
This is a lot trickier than I thought at first. To get this to work, we need to do this:

- in PlatformCALayerCocoa::clone(), also call setShapePath() when we're dealing with a LayerTypeShapeLayer
- in GraphicsLayerCA::fetchCloneLayers(), clone the mask layer in case we have both a backdrop and a mask and set the cloned mask to the cloned backdrop

But this doesn't fully fix the issue, because the way we clone the mask in GraphicsLayerCA::updateLayerMask() isn't quite correct. Ideally, we would clone the mask's PlatformCALayer independently in GraphicsLayerCA::updateLayerMask() and GraphicsLayerCA::fetchCloneLayers(), but this is made difficult due to the mask layer being touched from RenderLayerBacking and due to not having a way to get to the backdrop clone from GraphicsLayerCA since this is all internal to PlatformCALayer.
