Upgrade jQuery UI to v.1.12.0, draggable and droppable are not function stable as with older jQuery version.

Hi, 

I have an organization chart builder. After upgrade to jQuery 1.11.4, and jQuery UI 1.12.0. it doesn't drag and drop li and ul as stable as when I am using 1.7.2. 

Maybe I need to change code to accommondate jQuery 1.11.4, and jQuery UI 1.12.0. 

The code looks like below. Do I need to change the code? 

$(".myOrgDiv li").draggable({
      revert: "invalid",
      containment: "document",
      cursor: "move"
});

$(".myOrgDiv ul").droppable({
      accept: "li,ul",
      activeClass: "ui-state-highlight",
      tolerance: "touch",
      drop: function (event, ui) { 
          $(ui.draggable).detach().css({ top: 0, left: 0 }).appendTo(this); 
      }
});
