Description

I have two Controller Services: Service A and Service B. Service B references Service A.

If I enable Service A, and select to enable all referencing components, everything works well as long as all nodes succeed in enabling.

If a node other than the Cluster Coordinator fails, it will get kicked out of the cluster. It will then rejoin, and everything will continue to work smoothly.

But if the Cluster Coordinator gets kicked out of the cluster because it fails to enable, the service gets into a state where it can't be modified. Any attempt to modify it tells me an error: "Revision ... is not the most up-to-date revision. This component appears to have been modified"
