title: How should disabled <div> act?
body: <p>I noticed the following bug when using <code>$(selector).children().attr("disabled", "disabled")</code> where the children happened to contain a <code>&lt;div&gt;</code>.</p>
  
  <p><a href="http://jsfiddle.net/SZuqw/" rel="noreferrer">Fiddle</a></p>
  
  <pre><code>&lt;div disabled="disabled"&gt;
      &lt;input type="text" value="RAGE" /&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Basic testing says FF4/Chrome enable the field. IE9 disables the field.</p>
  
  <p>What is the expected behaviour? </p>
  
  <p>Same for any other non form element (<code>&lt;input&gt;</code>, <code>&lt;select&gt;</code>, etc)</p>
