Having problems when adding an element to sortable.

Having problems when adding an element to sortable.


Hello,
I'm attempting to dynamically add li elements to a ul tag, then use
the sortable's 'refresh' functionality.
The problem is that when a new li element is added, I attempt to sort
it by mouse-dragging, but it is not respecting the
forcePlaceHolderSize. There is no space given for the new tab when
dragging like the other pre-existing elements.
Also, when I have revert set to true, it throws the same new li
element up into the top left corner of the page after releasing the
mouse button to place the element between the other pre-existing li
elements.
The new li element still moves to the requested location between pre-
existing li elements, however.
I'm curious to know if this is a bug, or if I am possibly missing
something.
Any assistance is appreciated!
Thanks,
Ryan
The code below is fired
<code>
$(function() {
$('#sdTabHeader ul').sortable({
    revert: true,
    axis: 'x',
    distance: 10,
    forcePlaceholderSize: true,
});
$('#sdTabHeader ul').disableSelection();
});
