Sorry, but I did send Michal detailed information on this.
I just added bug for tracking and did not think anyone else will
be interested in all the boring details of  my build.

Oh, yes ofcourse. The file builds OK in lualatex. Here is the link

<https://12000.org/my_notes/CAS_integration_tests/reports/summer_2023_Rubi_4_17_3/test_cases/210_Hebisch/report.htm>

THere are over 10,000 subsections,. and tex4ht breaks down on
reportsubsection1100

Which is this

<https://12000.org/my_notes/CAS_integration_tests/reports/summer_2023_Rubi_4_17_3/test_cases/210_Hebisch/reportsubsection1100.htm#x1117-109610003.10.84>

If you click <NEXT> from the top of the above page you get error link not found
since no more subsections are processed after that. There is almost 9,000
subsections that should be there. All are not generated.

Yes, only HTML (mathjax) mode.

I build that code in reportsubsection1100.htm on its own, and it builds OK
with make4ht. It is only when the code is part of report.tex (the full
latex file which includes everything) where this problem is found.

I do not know xmlwf. I just see these domfilter and XML messages show
up and that is all. I really know very little about these.

But to help Michal, I send him ZIP file with everything in it so he can
reproduce this on his computer also.

It seems related to use tables, since that is the place where it fails.
