I've posted my comment on TeX.sx, and updated TeX4ht sources, so it should work soon.

I found that a problem in math generated after updated to latest TL. All math in chapter or section titles is messed up now. This used to show up OK before I updated to TL.

The math which is not in section or chapter title still shows OK. But why?

Here is a MWE



\title{my book title}



\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) $}

Compiled using

make4ht -ulm default -a debug index.tex 'mathjax,htm'

This is the HTML (see screen shot)

Notice all those \o stuff. Before updated TL this all worked OK and the math showed up OK in section and chapter titles. So something changed.

This is the raw HTML
