What I really do not understand is this:

When using `-a debug` then make4ht stops at first error:

    make4ht -ulm default -a debug a.tex "mathjax,htm"

But when wrapping the call by texfot then it does not stop at error

   texfot --tee=/dev/null --ignore="Overfull"
      make4ht -ulm default -a debug a.tex "mathjax,htm"

My question is why?

Should not the whole command stop at first error also when
adding texfot?
