/* By default async components don't have any way to recover, if component is
|

* 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.
