# 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! * There appear to be **intermittent timing issues with SOUP start-up on Chrome**: MathJax fixes sometimes don't get applied at all, and normal fixes sometimes seem to run before the DOM has finished loading. Reloading the page usually makes the problem go away. Investigating, any help is welcome! # Bug reports > **If you've found a bug in your SOUP, please post a comment below to notify me about it.** > This includes any unwanted side effects or regressions due to changes in the SE codebase.
