When possible we take the lowest common denominator approach to offer a consistent experience from browser to browser, and to avoid spending resources writing code that only a subset of users will be able to use anyways.

It's not just that it was only implemented by one UA.  It's also that
even in Firefox, multiple-range selections practically never occur.
The only way for a user to create them to to either Ctrl-select
multiple things, which practically nobody knows you can do; or select
a table column, which is also extremely uncommon; or maybe some other
obscure ways.  In evidence of this fact, Gecko code doesn't handle
them properly either.  Ehsan might be able to provide more details on
this if you're interested.
