If I create an issue on project.drupal.org and before submitting the issue click the preview button, instead of seeing the voting image all pretty like it is when viewing the issue, it is all in text and looks like this:

My issue votes
0
votes
0/5 total votes used

This is also true if I preview a comment on an issue. I'm not sure if this is a problem with project_issue_voting or one with another module used for the voting, but thought I'd report it in case this isn't already known.
