Windows leak into nearby workspaces

[Roshan George]

When windows are snapped to the left or right border, they leak into the neighbouring workspaces.

Steps to reproduce:
* Snap window to right edge of first workspace.
* Switch to workspace to the right.

Expected Behaviour:
* There should be no sign of the window on this workspace.

Actual Behaviour:
* The window border sticks out and over the edge.

Additional Notes:

Because of this bug, if you try to click on the launcher for the application on the Unity bar, it will merely focus the application instead of switching workspaces and taking you to it. This is incredibly annoying, and anyone unfamiliar with computers merely assumes the system has gotten stuck.

I also have this issue on 12.04 LTS while running Compiz desktop cube. Another way to replicate it is through the following:

1.) Open an application.
2.) Snap application to the right side of screen.
3.) Move to the neighboring right workspace.
4.) Click on application in the Unity bar.
5.) The workspace should spin over to the left workspace where the application is. However, it does nothing, as if the application is in the current workspace.

In fact if you look really closely, you can see that it does bleed over slightly. I don't get this to happen when I snap to the left, however.
