However, DrawingAreaProxy::Update message is dispatched while in AC mod in the following scenario. 1. DrawingAreaCoordinatedGraphics::exitAcceleratedCompositingMode calls DrawingAreaCoordinatedGraphics::display(WebKit::UpdateInfo&) 2. DrawingAreaCoordinatedGraphics::display(WebKit::UpdateInfo&) calls WebPage::updateRendering() 3. WebPage::updateRendering() executes JavaScript 4. JavaScript calls notifyDone 5. WTR::TestRunner::notifyDone calls WKBundlePageForceRepaint 6.
