> The {{Dispatcher}} contains a race condition when an instance is granted
> leadership and then quickly afterwards gets the leadership revoked. The
> problem is that we don't check in the recovered jobs future callback that we
> still have the leadership. This can lead to a corrupted state of the
> {{Dispatcher}}.
