I am always reluctant to move comments to chat, if they contain MathJax, because the chat interface doesn't support it. All math expressions are displayed as plain text, with the \$ delimiters, and no attempt to render what's in between.
Some users will move comments to chat "on my behalf", the reasons for which I understand. I know what chat is for, and I know what comments are for. But the consequence is that all the math becomes illegible, and further comments in chat can't employ MathJax either.
Is there any way to overcome this, or is there a chance that SE developers will enable MathJax rendering in chat?
