        Race condition in full screen controller, which leads to problem when web process crashes
        https://bugs.webkit.org/show_bug.cgi?id=61707

        Saw this while debugging a crash. We don't have a way to make regression tests for this
        kind of issue at this time.

        * UIProcess/mac/WKFullScreenWindowController.mm:
        (-[WKFullScreenWindowController exitAcceleratedCompositingMode]): Retain the controller
        here since we are keeping a pointer to it.
        (exitCompositedModeRepaintCompleted): Release the controller here.
