    // this view is visible above the platform view it is overlaying, so should respond to
    // accessibility exploration events. Forward those events to the accessibility delegate in
    // a special mode that will stop as soon as it reaches a platform view, so that it will not
    // find widgets that behind the platform view. If no such widget is found, treat the event
    // as unhandled so that it can fall through to the platform view.
