      Description

      Note: Possibly it's just an ugly side-effect of MDEV-20815, as I couldn't reproduce it with a "good" aggregate query, or without views.

      CREATE TABLE t1 (a TIME NOT NULL);
      CREATE VIEW v1 AS SELECT * FROM t1;
       
      SET SQL_MODE= 'ONLY_FULL_GROUP_BY';
      SELECT ROUND(a), COUNT(*) FROM v1;
       
      # Cleanup
      DROP VIEW v1;
      DROP TABLE t1;

      Also reproducible on 10.5.
      Couldn't reproduce with 10.3, but maybe it's because of different defaults.
      No obvious effect on a non-debug build.
