Hi Hilmar,thank you so much for checking this. So, if I read this correctly, this bug is an upstream issue?
Right now, it seems that the bug can be narrowed down to htlatex which is called by tex4ebook.
And yes, the .pdf and .dvi and even the .epub built without the mathml option are fine, but with the current discussion on accessibility and the major pain that trying to get an accessible .pdf out of latex sources is, it would be desirable to have something that does not rely on images for serving math.
BTW, the other system I tried (and where things worked) is not oldstable but buster, with TL 2019something.
