jQuery UI draggable Options scrollSensitivity

Scroll sensitivity is that when draggable item is being dragged to the edge of the container,
how many pixels the container scrolls.
$("#eleID").draggable({ scrollSensitivity: 100  });

Try to adjust scrollSensitivity by adjusting slider and to drag square to the bottom right corner
and just keeping dragging, to see the difference.
