[spread] When multiple windows of an app are open, clicking on one doesn't bring it to the foreground

A video will be worth a thousand words: http://ubuntuone.com/52EVJKJRh58uA2aaJiKsjZ

Addition information I can add:
- I have 3 terminator windows, one on each workspace
- The workspace that has firefox is the one that the window I'm clicking is in
- It happens consistently
- I am apparently using unity 2d, no idea when it switched itself from 3d to 2d :)

Steps to reproduce:

1. Open 2 nautilus windows on 2 separate workspaces
2. Open a window (e.g. firefox) on top of one of them
3. Go to the workspace containing the other nautilus window
4. Click on the nautilus icon in the launcher
5. Click on the nautilus window on the workspace where firefox is

Expected result:
Unity takes you to the workspace containing the nautilus window you clicked in, raises that window and focuses it.

Current result:
Unity takes you to the workspace containing the nautilus window you clicked in but focuses the window on top of it (firefox).
