title: "Drop-down" selected value not updated in HTML
body: <p>When I select a new value (3) in a drop down menu, I see that HTML still has the old value (10) as "selected".</p>
  
  <pre><code>&lt;option value="1"&gt;1&lt;/option&gt;
  &lt;option value="2"&gt;2&lt;/option&gt;
  &lt;option value="3"&gt;3&lt;/option&gt;
  &lt;option value="4"&gt;4&lt;/option&gt;
  &lt;option value="5"&gt;5&lt;/option&gt;
  &lt;option value="6"&gt;6&lt;/option&gt;
  &lt;option value="7"&gt;7&lt;/option&gt;
  &lt;option value="8"&gt;8&lt;/option&gt;
  &lt;option value="9"&gt;9&lt;/option&gt;
  &lt;option value="10" selected="selected"&gt;10&lt;/option&gt;
  </code></pre>
  
  <p>EDIT 1: the problem manifests itself when I clone the form. The cloned copy has its selected option reset. Is there a way to clone the selected value too?</p>
