MySQL connector does not filter out DROP TEMP TABLE statements from DB history topic

We have a source database which creates and drops a lot of temp tables during the day. We are seeing our dbhistory topic get flooded with a lot of messages like this:

"ddl" : "DROP TEMPORARY TABLE IF EXISTS `iready`.`xx_temp_table_test2` /* generated by server */"

We're not seeing any events for the corresponding create statements or any data events for the insert statements, which is good. It appears the DROP's are making it through the filter.
