Yes, IIRC mhtml-mode narrows so that a sub-mode won't try to examine
parts of the buffer that have a different syntax.  Whether you consider
this ugly or not is perhaps related to your stance on the whole widening
issue.  My view, though, is that there is a problem here intrinsic to
multi-modes: something has to tell the sub-modes about the relevant
boundaries in some way; so if the narrowing/widening stuff is changed,
something new will have to be invented here.
