> Currently, because of SOLR-8069, all the replicas in a shard can be put into LIR.
> If you restart such a shard, the valid leader will will win the election and sync with the shard and then be blocked from registering as ACTIVE because it is in LIR.
> I think that is a little wonky because I don't think it even tries another candidate because the leader that cannot publish ACTIVE does not have it's election canceled.
> While SOLR-8069 should prevent this situation, we should add logic to allow a leader that can sync with it's full shard to become leader and publish ACTIVE regardless of LIR.
