> On a 3 node OM HA setup, when a prepare is done with 1 OM down, it leads to a state where the leader and follower are fully prepared (Snapshot at last index and logs purged). When the 3rd node rejoins the quorum, it leads to an infinite installSnapshot loop between the leader and the 3rd node, and the system goes into a bad state until a restart is done.
