Indeed, I think that it was reported that spacing was too important, so 
the first paragraph in @item is not formatted as a paragraph, test is
simply dropped in <li> see line 3780 in Texinfo/Convert/HTML.pm 
in _convert_paragraph_type() 

   # no first paragraph in those environment to avoid extra spacing

But this can only be used for the first paragraph, there need to be 
a paragraph for the other paragraphs in @item.
