Yeah, this kind of crazy stuff is why I don't want to spec what Gecko
does.  I strongly suspect no one ever really thought about the
behavior, because multi-range selections almost never come up.  I'm
pretty sure typical authors stand no chance of realizing they exist,
either.  If I wind up speccing this, I'll make up something sensible.
