Armenian typography, letter t

This isn't really a Unicode question at all, but I know this list is
probably the best place to find the answer;-)

I'm putting a snippet of Armenian into a lecture slide, and the font
easily available to me renders the letter տ ARMENIAN SMALL LETTER TIWN
with a descending middle vertical, as indeed does the font in which my
editor is currently displaying.
However, the fonts my browser uses, and the few examples of printed
Armenian I have to hand, don't have a descender.

Is this a completely free stylistic variation, or does the choice have
any connotations? (I imagine it's to make it more distinct from ա AYB.)
