This MWE makes one small table of 2 rows of type p. The first row has has two
math equations. tex4ht only shows the first one but not the second. While
compiling with lualatex to pdf shows both as expect.

------------------------
\documentclass[12pt]{book}
\usepackage{amsmath,mathtools}
\usepackage{array}

\begin{document}
\begin{tabular}{|p{.6in}|>{\setlength\columnwidth{5.8in}}p{5.8in}|}\hline
ODE&\vspace{-2em}\begin{gather*}
y^{\prime}-1-2 x=0
\end{gather*}
With initial conditions
$
\begin{aligned}
[y \left(0\right) = 3]
\end{aligned}
$
\\ \hline
program solution&\vspace{-1em}
\begin{align*}
y \left(x \right) = x^{2}+x +3
\end{align*}
Verified OK. 
\\ \hline
\end{tabular}

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

the pdf shows the math on the right in first row. But HTML does not.

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

Here is the raw HTML generated. I see the missing math is there, but it is not
displayed but it is sitting there doing nothing.

Using TL 2022 on linux

>which tex4ht
/usr/local/texlive/2022/bin/x86_64-linux/tex4ht
>make4ht --version
make4ht version v0.3l
>

How to correct this so that the math shows up in HTML?
