Undo a up/down vote after a comment is left
A hypothetical situation:
- I downvote a question or answer and leave a comment as the pop-up notification suggests.
- The author responds to my comment in another comment explaining or clarifying something I missed or didn't understand.
- I go to remove my downvote, but can't because the question/answer has not been edited and my vote is locked.
Should comments, and in particular comments from the author, unlock votes?
