TeX4ht used to not start paragraphs explicitly in lists, but it caused 
issues with items that contained multiple paragraphs, so I changed that 
recently. It is possible to remove any paragraph spacing if item 
contains just one paragraphs, so it doesn't make any visual difference 
to the version without paragraph. 

I can make a DOM extension for make4ht that removes paragraphs in items 
that contain just one paragraph. It should be quite easy and more robust 
than any handling of this issue on the TeX side. 

Best regards,
