I think I have found some MathJax bug. (Although it's possible that it only manifests in my browser.) Probably discussing it will lead to lot of experimenting and taking screenshots. I do not want to fill Math Meta Chat with that.
Regardless whether or not it is actually a bug, I'd like to keep the room alive for some time. If some users have problems with using ChatJax or editing some MathJax formula, it might be better to take that into a separate room - so that it does not distract from the ongoing math-related discussion.
