Scroll on Droppable Demo Breaks Demo

[HershelSR]

To recreate:

1. Go to ​http://jqueryui.com/demos/droppable/
2. Drag the draggable box below the containing box to trigger a vertical scroll bar
3. Return the draggable box up to the target and release
4. Nothing happens
5. Move the box another tiny bit and now it works

Movie attached of bug for clarify

The option refreshPositions helps:

$('#draggable').draggable('option', 'refreshPositions', true);

Anyway it should be considered to take this example as a use case for the option refreshPositions.

The part of the current documentation ”… This solves issues on highly dynamic pages …“ is not very specific.
