Unstoppable from Heavy Armor skill tree is not preventing roots in PvP

Happens with Sorcerer, DK root and probably others.

You still get rooted wearing Snow Treaders when Unstoppable is active.

I'm rooted all the time while on pots, so I just stopped using them. Its been going on forever.

Here's proof.

0.9 seconds remaining on Unstoppable Brute
2.6 seconds remaining on DK Burning Talons

In other words, Unstoppable Brute had 2.3 seconds remaining when the root took effect and this should be impossible.
