Bug 445854

SUMMARY
I use the Win+<arrow key> shortcuts to snap windows to different sides of the screen and different heights/widths.

I happened to have the Kickoff launcher in focus when I performed that shortcut thinking I was in a different window.

What ended up happening was the Kickoff menu itself began to respond like a typical window and behaved in a similar manner to a regular window (the shortcut allowed me to expand the Kickoff menu to full screen height, full screen width, etc.)

The main issue with this is that I can't find a way to resize it back to the size it was initially since its default size is smaller than what the keyboard shortcuts allow. The expected behavior is that it shouldn't resize in that manner based on keyboard shortcuts

STEPS TO REPRODUCE
1. Open the Kickoff launcher
2. With the launcher open and in focus, press win+up arrow key (this can actually be any arrow key)
3. Observe the launcher size changing

OBSERVED RESULT
Launcher changes size

EXPECTED RESULT
Nothing happens as the launcher shouldn't be able to be resized in that manner (at least not without a simple way of changing it back to its default size)
