(ps. trying again. last attemtpt was rejected for some reason).

I think this problem is more serious.

I was now compiling an old file which has this

      \verb|\begin{luacode}....\end{luacode}|

And mathjax does not render it as verbatim at all. Gives my yellow error on the
page.

I also tried \begin{verbatim}, same problem. Please see MWE

====================
\documentclass[12pt]{article}
\begin{document}

\verb|\begin{luacode}....\end{luacode}|
\begin{verbatim}
\begin{luacode}....\end{luacode}
\end{verbatim}

\end{document}
=======================

Compiled using

      make4ht -ulm default -a debug foo3.tex "html,mathjax"

Error is "Unknown environment 'luacode'" on the page. Really? so how
does one tell mathjax not to look inside verbatim?

Any suggestion on the above one is appreciated.
