--- Comment #5 from Dean Jackson <dino at apple.com> ---
So either the logic of doing the preparation in Page::doAfterUpdateRendering() is incorrect for WebKit1, or something about the canvas backbuffer sizing causes a display to trigger early.
Calling setNeedsDisplay from prepare would probably fix this particular test, but would still be two paints - we need the prepare to happen before the paint.
Maybe it is the fact that the resize and paint happens inside a rAF?
