Empathy Icon Changes When Moving It In Plank

The new (white) Empathy icon changes into the old(blue) one when you move it in the dock. This is just a minor inconsistency issue.

To replicate the problem follow these steps:
1. Make sure Empathy is pinned to the dock.
2. Try and move that icon from its current position in the dock to another position.
3. While in the "moving state" the icon will have changed to the old one.
