Rocky has the same delete instance logical with master.

FYI there was an old bug related to this https://bugs.launchpad.net/nova/+bug/1308342 but the fix for that was reverted.

Overall I agree that we should be able to delete the instance even if it is stuck in task_state=DELETING state due to a compute restart. So I confirm the bug.
