That's the idea, yes.

I'm not sure. Have you checked how captions in other parts of
"ox-html.el"?

You may be right. In this case, we may use \eqref if MathJax is going to
be used (like your initial patch did), and do the above otherwise.

I don't think other captions allow this in "ox-html.el".

WDYT?
