Bug 495635

SUMMARY
It's possible to drag a window off the bottom of the screen.
With Firefox, the cursor still changes into the vertical resize variant, but nothing happens when I try to drag it.
When I try the same with Dolphin, the cursor doesn't react at all.

The window also doesn't respond to snapping using meta+arrow keys.

I found this resolved bug that seems similar, but not exactly the same.

STEPS TO REPRODUCE
(same as the above bug)
A. With firefox
1. Open a firefox window, and maximize it.
2. Push the cursor to the top of the screen.
3. Click and drag the cursor to the bottom of the screen.

B. With dolphin
1. Open a dolphin window
2. Drag it to the bottom, this will keep the title bar still visible at first
3. Grab the top of the window again, drag it all the way down

OBSERVED RESULT
The mouse can't interact with the window, and the window snapping shortcuts don't work.
It does still appear in the task switcher, so I can close it through there.

EXPECTED RESULT
At least part of the title bar should stay visible I think.
