 * failed, it is failed forever. This helper tries to remedy that by recreating
 * async component when retry is requested (by user). You need to emit the
 * `resetAsyncComponent` event from child to reset the component. Generally,
 * this should be done from error component but could be done from loading or
 * actual target component itself if needs to be.
