title: Firefox does not show tooltips on disabled input fields
body: <p>Firefox doesn't display tooltips on disabled fields. </p>
  
  <p>The following displays tooltip in IE/Chrome/Safari except Firefox:</p>
  
  <pre><code>&lt;input type="text" disabled="disabled" title="tooltip text."/&gt;
  </code></pre>
  
  <p>Why doesn't Firefox display tooltip on disabled fields? Is there a work around this?</p>
