title: Does jQuery not fire hover event on a disabled button?
body: <p>I'm implementing a form, whereby I'm wanting to disable a <code>button</code> and show a tooltip explaining why it's disabled on hover. However when a <code>button</code> is disabled the tooltip does not show. </p>
  
  <p>I've added a test case here, reproducing with just jQuery: <a href="http://jsfiddle.net/BYeFJ/1/">http://jsfiddle.net/BYeFJ/1/</a></p>
  
  <p>It seems that jQuery is not firing the event, or is the browser not firing the hover event?</p>
  
  <p>I'm using <a href="https://github.com/twitter/bootstrap/blob/master/js/bootstrap-tooltip.js">Twitter Bootstrap's Tooltip Module</a> and of course, jQuery.</p>
  
  <p>NB: I've also tried this with a wrapper around the button - but it swallows the hover state it seems, and I've also tried using an <code>input</code> element, to the same effect.</p>
