tex4ht destroys code alignment when using basicstyle=\small (with or without
font family being given) compare to when not using basicstyle. This only
happens in the HTML. The pdf is correct. Here is a MWE

--------------------------

\documentclass[12pt]{article}
\usepackage{listings}

\begin{document}

\begin{lstlisting}[language={},keepspaces=true,basicstyle=\small]
local case_one_gamma_entry := module()
    option object;
    export pole_location := 0;
    export pole_order    := 0;
    export sqrt_r        := 0;
    export alpha_plus    := 0;
    export alpha_minus   := 0; 
    export b             := 0;
end module;
\end{lstlisting}

\begin{lstlisting}[language={},keepspaces=true]
local case_one_gamma_entry := module()
    option object;
    export pole_location := 0;
    export pole_order    := 0;
    export sqrt_r        := 0;
    export alpha_plus    := 0;
    export alpha_minus   := 0; 
    export b             := 0;
end module;
\end{lstlisting}

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

compiled with

 make4ht -ulm default -a warning foo2.tex "mathjax,htm"


This is the HTML

No problem in PDF.

I like to user smaller font size in the HTML. Is there a way to make tex4ht
not change the source code when using smaller font size? I also tried
basicstyle=\ttfamily\small but no effect.

TL 2022.

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