    Description

      Testing, I just ran into a case where I have a region stuck in transition. We kept trying to open the region but were failing and eventually got stuck. Looks like a block was missing so region may never have been able to open but we likely shouldn't have the region stuck in transition.

      Here is some log snippet from master side only showing lines that mention the region that is failing:
