Double-Clicking on a Window in Desktop Switcher and moving mouse to screen edge creates window resize highlight

When I open the Desktop Switcher in Unity and Double Click on an application window inside a desktop to switch to that desktop, the desktop zooms, but moving the mouse to the either the top, left or right edges of the screen causes the orange overlay showing how a window would be maximized on one of those edges appears. It does not go away until I grab the window and drag it anywhere. This is especially a problem with maximized windows.

Double-clicking on the background itself to zoom into a given desktop does not replicate this behavior. Clicking on the application window, then the desktop clears whatever state has been erroneously set, though clicking on the application window without then clicking on the desktop does not.

Steps to reproduce:
1. Start Unity
2. Open any application window
3. Open the Desktop Switcher
4. Double click on the Application Window to zoom into the desktop
5. Move the mouse to the top edge of the screen, the orange transparent overlay will appear
