RemoteScrollingCoordinator::scheduleTreeStateCommit() can be called in the middle of a compositing update. Instead of just handling that scrolling tree commit in the current update (which is what would happen if it called into Page::scheduleRenderingUpdate()), it triggers another update after the current one, because it just calls the WebKit2-level drawingArea()->triggerRenderingUpdate().
