if you go through FrameView::repaintContentRectangle or something that calls it you'll get the layout test tracking for free, since it's implemented at that layer.  I think calling repaint() on the mainFrame()->contentRenderer() will do exactly what you want (although be sure to null-check it before dereferencing it), mind checking if that's the case?
