title: keep :hover on dragging jquery element
body: <p>I have a site with an element where the CSS class has a :hover state showing an outline.
  This works ok.
  however:</p>
  
  <ol>
  <li><p>When I start to drag this object (part of a sortable) the hover effect is removed, Jquery draggable doesn't keep the :hover state.</p></li>
  <li><p>Once dropped, the css hover state won't reappear, I have to leave the object and reenter it to make the css effect appear.</p></li>
  </ol>
  
  <p>Any way to solve these issues?</p>
