Comment 2 for bug 502882

I did take a look myself at fixing this as a drive-by while working on other duplicate issues, but fixing this requires firing off an API request to get the duplicate's title, and that's a few more lines of code and callbacks than I want to introduce alongside my other current changes.

Like Curtis notes, this bug doesn't exactly apply anymore since we need a general AJAX-based "add tooltip titles to bug numbers" solution now, but I still think we need to be mindful that this has to happen after changing the DOM when marking a bug as a duplicate. So we should keep this bug open. I will, however, downgrade the priority since it requires other work to be done first.

Cheers,
