Answer 1

The mouse is constrained the same on all edges. The mouse itself is the very point of the arrow. The rest of the arrow just hangs off of this, and has no “collisions”.

Since the arrow hangs down and right, it disappears when the mouse is in the bottom right – the arrow hangs offscreen. When the mouse is up and left, the arrow hangs down and right; it hangs in the visible screen.
