SUMMARY
Corner barrier ignored when dragging window.

STEPS TO REPRODUCE
1. Have 2 screens (left/right)
2. Enable corner barrier (it's enabled by default). More specifically, I have "Corner barrier" enabled, however "Edge barrier: None".
3. Drag window title to move a window
4. Move mouse pointer all the way to the top of the left screen
5. Move mouse pointer along the top line of the screen to the right into the top-right corner (use case: auto-resize the window to 1/2 or 1/4 of the screen)

OBSERVED RESULT
If you move mouse pointer too far to the right, to move to the right screen immediately.

EXPECTED RESULT
Should respect corner barrier.
