STEPS TO REPRODUCE: 1. Load a Vanilla Forums discussion, e.g. on Mozilla's intranet instance at https://intranet.mozilla.org/forum/comments.php?DiscussionID=902 2. Type a few lines of text in the comment field (e.g. 'a b c d' each on its own line) 3. Click "Preview Post" ACTUAL RESULTS: The contents of your "Preview" comment don't get painted. Instead, you get a duplicate of the chunk of page that was pushed downards to make room for the preview. (If you click the window titlebar, or click in a different window, then it repaints correctly.)
