I noticed that the site does not seem to use the begingroup extension for MathJax, which could possibly lead to bugs: For example, a macro defined in a comment to a question could have an unexpected affect on an answer below it.

\newcommand
appearing in a comment persists until that statement rolls off the scrollback. This can mess up the $\LaTeX$ later on if the command is not done right. We have unofficially outlawed\newcommand
etc. In chat. $\endgroup$ – robjohn♦ Jan 1 '13 at 18:18
