seems there is no more to do with mathjax references (unfortunately)? closing, feel free to reopen if that's wrong ...

This is something that is not easily solvable. The labels inside math are not processed by LaTeX at all, so the labels are not saved. MathJax itself supports some form of referencing, when \eqref command is found in the HTML code. So one possible solution is to provide a custom command, that is written as \eqref in the HTML. See this answer of mine:

https://tex.stackexchange.com/a/378359/2891

It also discuss another option, which is pre-processing of the TeX file, but it is a bit more complicated. It is necessary to use a custom command to reference to math, because if normal \ref was used, you would lose the referencing support for tables, sections, etc.

Using htlatex with the mathjax option causes references created with \ref to fail. Minimal example:

\documentclass{article}
\begin{document}
\begin{equation} \label{a} a=b \end{equation}
\ref{a}
\end{document}

...saved as minimal.tex. The command

htlatex minimal "html"

produces an html file with a working link at \ref{a}, but

htlatex minimal "html,mathjax"

produces just (??) even after multiple passes. Debian buster, tex4ht.c 2018-06-30-15:36 (from the debian repos)
