I see. No problem. I just have to remember to add save_size next
time when installing new version of TL. I need to add this to my
tex4ht cheat sheet.

The time to compile did not change after updating TL. About 2-3 hrs to
compile the HTML, and about 5 minutes for the PDF.  Here is the actual
web page itself


I think the long time due to having many tables. I am not sure why. If I was
using svg for math instead of mathjax, the HTML would take 2-3 days to compile.

I just posted question about it at tex.stackexchange.com


May be this is how tex4ht was before and I did not notice. it is related to link
wrapping inside table. I could not find solution for this so far after
trying for some time.

Thank you
