Latex math environment flalign not converted to markdown math

[asmaier]

Explain the problem.

When trying to convert the following example LaTex file test.tex :

\documentclass[12pt,a4paper,twoside]{book}
\usepackage[intlimits]{amsmath}	
\begin{document}
% examples taken from amsmath user guide
\begin{equation*}
a=b
\end{equation*}

\begin{equation}
a=b
\end{equation}

\begin{equation}\label{xx}
\begin{split}
a& =b+c-d\\
& \quad +e-f\\
& =g+h\\
& =i
\end{split}
\end{equation}

\begin{multline}
a+b+c+d+e+f\\
+i+j+k+l+m+n
\end{multline}

\begin{gather}
a_1=b_1+c_1\\
a_2=b_2+c_2-d_2+e_2
\end{gather}

\begin{align}
a_{11}& =b_{11}&
a_{12}& =b_{12}\\
a_{21}& =b_{21}&
a_{22}& =b_{22}+c_{22}
\end{align}

\begin{flalign*}
a_{11} + b_{11}& = c_{11}&
a_{12}& =b_{12}\\
b_{21}& = c_{21}&
a_{22}& =b_{22}+c_{22}
\end{flalign*}
\end{document}

via

pandoc --wrap=preserve -s -t markdown -f latex -o test.md test.tex

I get the following result

$$a=b$$

$$a=b$$

$$\label{xx}
\begin{split}
a& =b+c-d\\
& \quad +e-f\\
& =g+h\\
& =i
\end{split}$$

$$\begin{gathered}
a+b+c+d+e+f\\
+i+j+k+l+m+n
\end{gathered}$$

$$\begin{gathered}
a_1=b_1+c_1\\
a_2=b_2+c_2-d_2+e_2
\end{gathered}$$

$$\begin{aligned}
a_{11}& =b_{11}&
a_{12}& =b_{12}\\
a_{21}& =b_{21}&
a_{22}& =b_{22}+c_{22}
\end{aligned}$$

::: flalign*
a\_11 + b\_11& = c\_11&
a\_12& =b\_12\
b\_21& = c\_21&
a\_22& =b\_22+c\_22
:::

Curiously all amsmath environments are converted to markdown math except for flalign .
I think flalign should also be converted to a math environment in markdown.

Pandoc version?
I'm using pandoc 3.1.13 on Mac OS Sonoma 14.3.1 .

What would be the proper fallback for this within math mode?
aligned?

[asmaier]

Yes, I believe that is probably the best solution for now.

Thank you.
