I have two polls on a page. If I vote on one, and detele my vote, when I hover over the other poll's number of votes, they disappear. They reappear once I vote in that poll too, but I'd like to avoid this bug altogether if possible.
To be more specific, the text in the span that contains the number of votes disappears from the HTML, it is not a styling issue.
