I'm trying to suggest an edit to a question and I wanted to verify the tags were correct, but hovering over the tag while on the edit page (note that since it's a suggested edit, it's not the inline editor) doesn't bring up the popup with the excerpt. Likewise, when writing this question, I can't see the excerpt popup for tags I have already selected.
When I view a question normally, the tag popups work fine, only the edit and "ask a question" pages don't show them. I have to click on the tag to edit it and use the suggested tag list to see the excerpts.
I see this issue on Windows 7x64: Chrome 13, IE 8, and Firefox 5.
