    // No JS application has started yet, or resumed. This can happen when a ReactRootView is
    // added to view hierarchy, but ReactContext creation has not completed yet. In this case, any
    // touch event dispatch will hit this codepath, and we simply queue them so that they
    // are dispatched once ReactContext creation completes and JS app is running.
