I just ran into this topic in the Reopen Votes queue. The reason for the Reopen Vote showed 'it has been edited', so I looked up what had been changed, and saw that the topicstarter had added a moderation flame at the end ("Shame this topic is closed").
Since the topic itself hadn't been changed I wasn't planning on disagreeing with the democratic close decision, so I just edited the post to undo the vandalism and reject the reopen vote afterwards. Except that my editing was automatically interpreted by the system as a reopen vote, and so it's currently going back to the rounds with my endorsement. Without warning I inadvertently took an action exactly opposed to my intentions.
I probably should've used rollback instead (hopefully that doesn't auto-cast the reopen vote?), but still in this case I think I should've gotten a warning anyway that this was about to happen? Can editors please get a nice popup like with bounties saying "does your edit mean you wish to nominate it for reopening?" or something?
