    Description

      Attached tests (from mariabackup suite) do show that mariabackup 10.1 does rollback of uncommitted transactions despite flag --apply-log-only :

      FOUND /Rollback of trx with id / in current_test 
      # expect NOT FOUND

      10.2 as well as xtrabackup 2.3.9 is not affected: 

      NOT FOUND /Rollback of trx with id / in current_test 
      # expect NOT FOUND
