https://tex.stackexchange.com/questions/669581/tex4ht-fails-on-including-image-with-math-in-caption-after-loading-hyperref-pack

his MWE compiles OK with lualatex but fails in tex4ht once hyperref is added.

-------------------------------------------
\documentclass{article}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage{hyperref}

\begin{document}

\begin{figure}
\includegraphics[width=0.5\textwidth]{example-image-a}
\caption{Phase plot $y^{\prime \prime}\left(t \right)+9 y \left(t \right)-\left(\left\{\begin{array}{cc}
8 \sin \left(t \right) & 0<t <\pi
\\

1. & \pi <t

\end{array}\right.\right) = 0$}
\end{figure}

\end{document}
----------------------------

And now

make4ht -ulm default -a debug foo.tex "mathjax,htm"
gives

/usr/local/texlive/2022/texmf-dist/tex/generic/tex4ht/html5.4ht))
(/usr/local/texlive/2022/texmf-dist/tex/latex/l3backend/l3backend-dvips.def)
(./foo.aux) (/usr/local/texlive/2022/texmf-dist/tex/latex/base/ts1cmr.fd)

<argument> \EndPicture

l.14 \end{array}\right.\right) = 0$}

?

Removing hyperref it compiles clean. (ps. I used test image above so it can compile as is).

Is there a workaround for this?
