2. Drag to snap on edge with another monitor

OBSERVED RESULT
1 pixel extending to bordering monitor

EXPECTED RESULT
Whole window contained within one monitor

ADDITIONAL INFORMATION

Now I see that there are 2 points at which the window is snapped. Firstly the window is snapped to the border of monitor correctly, but a delicate move forward can push it to another, stronger snap point, at which it results in what I previously described.
