I wanted to find out what the result of thew voting was, and found the voting still open with a negative time to go. That ran approximately 5 minutes, before the voting was displayed as finished, and its result became visible.

During the negative time, I was offered all usual links such as make, revoke, or change my vote, etc. So as not to do semthing undesired, I only reconfirmed my existing vote, which was accepted. I was expecting an error message saying that the time to vote was over.
