      Description

      please run the test with --repeat=100 and use it just to reproduce the problem.
      it is repeatable on 10.3-10.6, not on 10.2

      change  master to master_host='localhost', master_port=3306, master_user='root';
      stop slave;
       
      connect (c1,localhost,root,,);
       
      --connection c1
      start slave;
      --send change  master to master_host='localhost', master_port=3306, master_user='root'
       
      --connection default
