  NOTE: This is currently BROKEN in WebKit. We're clipping the viewport of <foreignObject> correctly,
-       though for each positioned object a RenderLayer is created, that has no knownledge of the
-       size of the <foreignObject> viewport - as <foreignObject> doesn't create a RenderLayer.

        So for now, you'll see an unclipped content area, just as if overflow was visible.
