Do not update css when draggable is disabled
<p>On this fiddle when I click disable'Li Point1' the text ebcomes greyed out <a href="http://jsfiddle.net/adrianjsfiddlenetuser/Q9sHz/14/" rel="nofollow">http://jsfiddle.net/adrianjsfiddlenetuser/Q9sHz/14/</a></p>

<p>Can the original styling of the element be maintained(not greyed out) ?</p>
