Hitting the rate limit when flagging comments breaks the flag dialog
After flagging a comment and attempting to flag another under 5 seconds, you get the notification that you have to wait at least 5 seconds. After waiting 5 seconds, it says "Please confirm flagging reason" or something to that effect. There is no box to select the flagging reason on your third attempt at hitting the button. You have to refresh the page to continue flagging additional comments.
