title: jquery ui sortable - clicking scrollbar breaks it
body: <p>Scrolling a div that is within a <code>.sortable()</code> container will start dragging the div when you release the scrollbar</p>
  
  <p>In the fiddle, there are 3 different sortables, 1 of them is a scrolling one</p>

  <p>Bug: click on the scrollbar and drag it up or down to scroll through the content, when you release the mouse, the div starts to drag, which makes it follow your mouse around and there is no way to unstick it without refreshing the page.</p>
