I found a problem in TL 2023 on same document and same command, where now
tex4ht duplicates the TOC in two columns instead of spreading the TOC over the
two columns as it always did before.

Same document, same command. So something changed. The question is how to make
it behave as it did in TL 2022? Do I need to change something in the command
or in the latex?

I have document where in HTML only, I wanted to make the TOC spread over 2
columns because it is very long so I am using multicol package. This has been
working ok for many years.

Here is MWE

---
\documentclass[12pt,titlepage]{article}
\usepackage{multicol}

\begin{document}
\title{my book}
\author{me}
\date{\today}
\maketitle

\ifdefined\HCode 
\Configure{tableofcontents*}{section}
\fi 

\ifdefined\HCode 
\begin{multicols}{2}
{
\tableofcontents
}
\end{multicols}
\else 
\tableofcontents
\fi 

\section{section 1}
text
\section{section 2}
text
\section{section 3}
text
\section{section 4}
text
\section{section 5}
text
\section{section 6}
text

\end{document}


Compiled using

make4ht -ulm default -a warning main.tex 
 'mathjax,htm,fn-in,0,notoc*,p-width,cut-fullname'

This is the output on a Linux running TL 2023
