We observed recently that when a task that is waiting on release coordinator approval happens to fail (e.g., due to a database maintenance window lasting longer than it takes for the 3 retries to get used up), the UI gets into a confusing state.

It will continue to show the failed task with a "pending" state and an "approve" button. It's better if it would begin to show "failed" state and "retry" button. It shows correct state after relui is restarted, which can be used as a workaround.

This is the tracking issue to make it unnecessary to restart in that situation (as rare as it might be).
