[tex4ht] [bug #589] tex4ht no longer shows table of content when using split level

Tue Dec 27 03:44:13 CET 2022

The title of this bug should be

"All math in chapter or section titles is messed up now"

I copied the wrong title from the last bugI entered.

I did not know how to change it in https://puszcza.gnu.org.ua/bugs/?589
after that.

If someone knows how to edit the bug and change the summary to the above
that will be good.

Thanks
