Fixed missing tiles after history back
https://bugs.webkit.org/show_bug.cgi?id=310153
Reviewed by Simon Fraser.
A blank page was shown after history back if the focused element was placed in
far down the page. LocalFrameView::scrollToFocusedElementInternal() scrolled to
the focused element. However, a RenderLayerBacking wasn't created when
scrolling to the focused element, and GraphicsLayer::setPosition() was not
called. Then, the coverage area was miscomputed, and tiles were missing.
scrollToFocusedElementInternal() should update compositing layers before
scrolling.
