jquery.ui.sortables Fails to sort to last position with <div> tags

Reported by: malfist Assigned to: joern
Type: bug Priority: major
Milestone: 1.3 Component: web
Version: 1.2.5 Keywords: ui, jquery.ui, sortables
Cc: Needs: Review

Description

When applying sortable to the following list, the element with text in the second div tag ("blah") can not be dragged to the last position. It can be dragged to the next to last then others move above it. 

<ul style="position: relative;" class="ui-sortable" id="sortable_left">

Update:

This only happens with some have content and some do not. When all have content in the second div, it moves freely. Although they sometime disappear.

An additional test. Those id's have no css linked to it. You cannot drag the first list item below the last. 

<ul id='sort'>
		<li><div>1<div><br />&nbsp;2</div></div></li>
		<li><div>2</div></li>
		<li><div>3</div></li>
		<li><div>4</div></li>
	</ul>
</div>
<script type='text/javascript'>
	$("#sort").sortable({ items: "li", revert: true, tree: true });
</script>

Attaching my version (grabbed from ui.jquery, personalized (contains everything). I have modified it where I think the error is occurring. drag: function(e) acts funny when the nested (or multipule does not have to be nested) is dragged, reporting the item number and the max items differently than the rest of the items.

Nevermind I cannot do that. I'll see if I can copy and paste here.

That didn't work either.

The drag function starts at line 2519, where I think the error is, is in the if inside the for loop (lines 2529-2533), 10 lines down.
