This issue causes yet another problem, which is present in MariaDB as well (I didn't test, see only code)

 

The behavior is OK if Node 1 does not disable SET SESSION wsrep_on=OFF;. But as per documentation wsrep_on controls only replication from this node to the cluster. It does not matter what is its value, replication from other nodes is still accepted.

So it does not matter if we set it to ON or OFF - row from Node 2 should not be replicated to Node 1 if Node 1 has global read lock.
