Known bugs
Markdown editor hooks (e.g. mse224533, math11392, boardgames1152, french347) sometimes fail to run on Opera, apparently due to a race condition where the editor gets initialized before SOUP has a chance to add the hook. Reloading the edit page usually fixes the problem.
The over-wide comments fix reserves a fixed amount of horizontal space for the comment vote counts and vote / flag buttons. For comments with high vote counts, especially on sites with wide vote / flag icons, this can cause the vote count to overflow to the left. While this has no practical effect on usability, it can look a bit funny, especially when the comment is hovered over.
