"Prevent this page from creating additional dialogs" doesn't work
When I go to a google doc in high security mode (see #22478 (moved)), it creates multiple dialogs. There is an option in the dialogs to "Prevent this page from creating additional dialogs".
When I check it and click ok, it doesn't work: the page keeps creating dialogs.
