Error Message duplicating when maintenance mode activated

Hello,

when the maintenance mode was activated, we didn't have the ability to see the popover preview of posts.

We saw a message "You're not authorized to....", but each time i tried to see a post, this message was duplicated (see the attached .gif animation).

I didn't tried, but maybe it's the same, when user doesn't have permissions to see the post or user profile...
