Let's say I upvote a comment, but 2 seconds later I change my mind.
This is the scenario:
- Click on the comment -> upvoted
- Double-Click on the comment ->
Are you sure you want to undo your upvote on this comment? You will not be able to upvote it again.
- Click on Ok -> the alert disappears
You may only submit a comment vote every 5 seconds.(and the comment vote is still there).
I think the comment vote should just be cancelled at this point.
However this happens only when a user tries to do all the above within 5 seconds.
