title: ui.item.parent() doesn't return ul
body: <p>I am using sortable plugin of jQuery UI. This is my code:</p>
  
  <pre><code>   $(element).sortable({
          handle: ".handle",
          placeholder: "drophover",
          connectWith: '.day ul',
          helper: "clone",
          scroll: false,
          revert: 100,
   receive: function (event, ui) {
      //ui.item.parent doesn't return ul in console.log. However ui.item outputs li in //console.log
  });
  </code></pre>
  
  <p><strong>Edit:</strong></p>
  
  <p>If I do <code>$(ui.item).parent()</code>, it still doesn't work. Attached is the image from my console.log</p>
  
  <p><img src="https://i.stack.imgur.com/amQlE.png" alt="enter image description here"></p>
  
  <p>Please see that <code>ul</code> is not outputted and my length is <code>0</code>.</p>
  
  <p><strong>2nd Edit:</strong> It looks like we can't get parent inside 'receive' event of sortable. If I try it inside update, it works.</p>
