New Glitch: Twin Emperor Vek'lor + Evolve

I was playing my fancy new No-Cthun Vek'Lor Evolve Shaman! and I found a new visual glitch after a couple games so I went to face the Innkeeper to recreate it.

If you cast Evolve immediately after playing Twin Emperor Vek'lor, the evolved minion will spawn before the taunt image for the second Emperor is applied, leaving a floating taunt image.

Proof!
