[QUERY TAB IN UI] Not able to change the query if it has two semicolons in the end

Please issue any query with 2 ';;' in the end as:
select * from default WHERE department = 'Support' and ( ANY i IN default.hobbies.hobby SATISFIES i = 'art' END) order by hobbies.hobby asc limit 2;;

It gives the right error message but I am not able to change the query which is typed.
This issue is seen in chrome and safari.

This is a regression from 4.6.
