Drag & Drop issues in TreeView

[Igor]

Hello, I am having some issues with TreeView that I need help resolving:

Issue #1: 

Below code works, and sprites show up, until you drag an item. After that <span> tags get stripped.

<ul id="hosts">

    <li id="host1"><span class="maas-sprite server"></span>host1</li>

    <li id="host2"><span class="maas-sprite server"></span>host2</li>

    <li id="host3"><span class="maas-sprite server"></span>host3</li>

</ul>

  

$('#hosts').kendoTreeView({

        dragAndDrop: true,

});

Issue #2:

When moving last item from one TreeView to another, it is impossible to drag anything back.

How do i fix this??

Ok, I solved issue #1 by using "spriteCssClass" property in my data source.
But i still havent solved the issue #2 with being unable to drag elements back into a now empty treeview.
