All reviewed patches have been landed.  Closing bug.

Very weird. In this particular test, the frame reserved space for a vertical scrollbar (resizing the RenderView to 785x600) when it doesn't need to. This leaves a gray background (which doesn't look like scrollbar) on the right hand side of the screen, with a shadow near document boundary.

I can avoid triggering this in my patch, but it feels like a bug to me.
