Use include/sync_with_master_gtid.inc instead of --sync_with_master to avoid a race in the test case. In parallel replication, the old-style slave position (which is used by --sync_with_master) is updated out-of-order between parallel threads. This makes it possible for the position to be updated past DROP TEMPORARY TABLE t2 just before the commit of INSERT INTO t1 SELECT * FROM t2 becomes visible. In this case, there is a small window where a SELECT just after --sync_with_master may not see the changes from the INSERT.
