Steps to reproduce:
1. Open two windows and place them in the same point on the screen
2. Move the mouse to the minimize button
3. Click the minimize button twice
What should happens?
The two windows should minimize with the nice effect.
What happens instead?
The first windows (on top) minimizes with the effect, but the second one simply disappear.
This bug is easily noticeable if you set the dconf keys com.canonical.unity.minimize-count to zero and com.canonical.unity.minimize-slow-duration to something high (like 2000).
