我发现更新到最新 TL 后生成的数学公式存在问题。现在章节和/或部分标题中的所有数学公式都乱了。在我更新到 TL 之前，这个公式显示正常。我以前用过这个很多年，没有出现过任何问题。
不在章节标题中的数学仍然显示 OK。
这是 MWE
\documentclass[12pt]{book}%
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{hyperref}
\begin{document}
\frontmatter
\title{my book title}
\author{me}
\date{\today}
\maketitle
\ifdefined\HCode
\Configure{tableofcontents*}{chapter}
\TocAt{chapter,section}
\TocAt{section,subsection}
\TocAt{subsection,subsubsection}
\TocAt{subsubsection,paragraph}
\fi
\tableofcontents
\mainmatter
\chapter{First order ode $F\left( x,y,y^{\prime}\right) =0$}%
The equation is $F\left( x,y,y^{\prime}\right) =0$
\section{First order linear in derivative $F\left( x,y,y^{\prime}\right)=0$}%
These are first order ode's which are linear in $y^{\prime}$.
\subsection{Quadrature ode $y^{\prime}=f\left( x\right) $}
data
\subsubsection{Introduction}

\end{document}
使用编译
make4ht -ulm default -a debug index.tex 'mathjax,htm'
这是 HTML
注意所有这些\o内容。在更新 TL 之前，这一切都运行正常，数学运算在章节标题中显示正常。所以有些事情发生了变化。
这是原始 HTML

当您在 MathJax 模式下遇到 TOC 中的数学命令问题时，通常需要使用命令声明有问题的命令\fixmathjaxtoc。在这种情况下，问题出在\left和 上\right，因此您可以使用以下方式声明它们：
\Preamble{xhtml}
\fixmathjaxtoc\left
\fixmathjaxtoc\right
\begin{document}
\EndPreamble
结果如下：
