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.
