title: Turn off jQuery UI tooltip for certain elements
body: <p>For simplicity, I'd like to enable the jQuery UI tooltip widget on all elements of the page:</p>
  
  <p>Then disable it for certain elements or elements and their descendants.  But this doesn't seem to work:</p>
  
  <pre><code>$(document).tooltip({ track: true });
  $('#menu *[title]').tooltip({ disabled: true });
  </code></pre>
  
  <p>My <code>$('#menu *[title]')</code> selector seems to work as I expect, getting all descendant elements that have a title attribute of the #menu element.</p>
  
  <p>So why isn't the <a href="http://api.jqueryui.com/tooltip/#option-disabled">disabled</a> option working in <code>.tooltip({ disabled: true });</code> to disable the tooltip on those elements? Is there another way and/or better way to accomplish this?</p>
