+#
+# Purpose:
+#   If a fake Glle event follows a Gtid event, we need to ensure the rest of
+# the group should not terminate at the Glle event. MDEV-28550 revealed that
+# a Glle would terminate the event and upon reconnect, the DDL would be lost.
+#
+# Methodology:
+#   Force the primary to send a fake GLLE event after a GTID on a "reconnect"
+# and ensure that both 1) the replica does not error, and 2) the original
+# command within the GTID is executed.
+#
+# References:
+#   MDEV-28550: improper handling of replication event group that contains Gtid_log_list_event
