fyi,
This might be known issue. This MWE generate mathml that mathjax does not like.
--------------------------------
\documentclass[12pt]{article}
\usepackage{amsmath}
\begin{document}
\[
\operatorname{I_{\frac{4}{3}}}
\]
\end{document}
-----------------------
compile with:
htlatex foo.tex "nma,htm,pic-align,charset=utf-8,notoc*" " -cunihtf -utf8"
The foo.htm file, on firefox shows an error
Unexpected text node: 'I'
the file nma.cfg just loads the mathjax. Here it is in case someone
wants to reproduce the above:
-------------------------------
cat nma.cfg
\Preamble{xhtml,mathml,ext=htm,charset="utf-8",p-width,pic-align} %does
mathml, not png !
\Configure{VERSION}{}
\Configure{DOCTYPE}{\HCode{<!DOCTYPE html>\Hnewline}}
\Configure{HTML}{\HCode{<html>\Hnewline}}{\HCode{\Hnewline</html>}}
\Configure{@HEAD}{}
\Configure{@HEAD}{\HCode{<meta charset="UTF-8" />\Hnewline}}
\Configure{@HEAD}{\HCode{<link
rel="stylesheet" type="text/css"
href="\expandafter\csname aa:CssFile\endcsname" />\Hnewline}}
\Configure{@HEAD}{\HCode{%

}}

></script>\Hnewline}}
\Configure{@HEAD}{\HCode{<style type="text/css">\Hnewline
.MathJax_MathML {text-indent: 0;}\Hnewline
</style>\Hnewline}}
\begin{document}
\EndPreamble
------------------------------------------------
Here is the HTML source for the above:
---------------------------------------------
<div class="par-math-display"><!--l. 8--><math
