Que rune bug while playing Druid

I was under the impression that runes granted all bonuses activated in the skill tree.

Que rune - Invoke the Druid’s Earthen Bulwark

Runeword: NeoQue - Graceful Fortress

I’m using the Que rune on my Druid and it is not granting me Unstoppable when it procs. I have ‘Enhanced Earthen Bulwark’ activated in the skill tree.

EDIT#2: It is still a bug. I’m not getting unstoppable with rune.
