# Known bugs * Markdown editor hooks (e.g. [mse224533](http://meta.stackexchange.com/q/224533), [math11392](http://meta.math.stackexchange.com/q/11392), [boardgames1152](http://meta.boardgames.stackexchange.com/q/1152), [french347](http://meta.french.stackexchange.com/q/347)) 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 kluge used to monitor WebSocket messages on SE chat doesn't seem to work on Opera, so SOUP falls back to polling for changes at ½ second intervals. This works, but is less efficient. * SOUP does not work (at all) on Scriptish 0.1.11, because document.documentElement is not available at document-start. Apparently, this is [a bug in Scriptish](https://github.com/scriptish/scriptish/issues/16) that has been fixed in [Scriptish 0.1.12](https://addons.mozilla.org/fi/firefox/addon/scriptish/versions/?page=1#version-0.1.12), but that version was [never properly approved for distribution on addons.mozilla.org](https://github.com/scriptish/scriptish/issues/239). * The new [mse154788](http://meta.stackexchange.com/questions/154788/why-are-comments-overlapping-the-sidebar) / [stats1987](http://meta.stats.stackexchange.com/questions/1987/rendering-error-comments-with-mathjax-syntax-errors-overflow-their-boxes) fix in SOUP v1.22 may sometimes [add spurious scroll bars to comments on Chrome](http://meta.stackexchange.com/questions/240352/horizontal-scrollbar-for-comment-container). This *should* hopefully be fixed in SOUP v1.24, but since I can't personally reproduce the bug, and since the underlying cause is uncertain (I suspect a bug in Chrome), it's hard to be sure. If it still happens for you, please let me know! * MathJax config fixes sometimes don't get applied on Chrome, apparently due to a race condition. Reloading the page usually fixes it.
