Moving the mouse over the red box will trigger the mouse intent functionality. If your mouse moves outside the yellow target area, then the it's determined the intent is to move out of the element. Mouse movements in the yellow area are monitoring to try and detect intent of the user. If your mouse comes to rest in the yellow area, then we assume you meant to move away from the active element. If your mouse moves for too long inside the yellow area, we will also assume the user is intending to target outside the element.
NOTE: The actual target area and what is shown in yellow differ a little, it's not an exact rendering--it's pretty close, just do to the differnence in how radius borders are rendered.
