    Description

      This is followup to https://jira.mariadb.org/browse/MCOL-6297

      The query there had one of its predicates incorrectly pushed down to one of UNION constituents. The predicate that was incorrectly pushed referenced simple column to table alias and it was pushed to the UNION part with the same alias, but completely different table.
