SUMMARY
Panels attached to one screen that are not drawn on the second screen block window movement as if the panel stretches all the way across the second screen.

STEPS TO REPRODUCE
1. Have 2 screens side by side
2. Attach a panel to the top of the main screen
3. Try to move a window to the top of the secondary screen

OBSERVED RESULT
The window will be blocked at the y-coordinate of the panel, that is on the other screen.

EXPECTED RESULT
The window should only get blocked by the visible parts of the panel.
