title: jQueryMobile data-native-menu="true" doesn't work on browsers
body: <p>I'm playing with jQueryMobile and with the widget "select". </p>
  
  <pre><code>&lt;select id="list"  data-placeholder="true" data-native-menu="false" multiple="multiple" data-iconpos="left"&gt;
      &lt;option&gt;Country&lt;/option&gt;
      &lt;option value="all"&gt;All&lt;/option&gt;
      &lt;option value="usa"&gt;USA&lt;/option&gt;
      &lt;option value="br"&gt;Brazil&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>That code works OK in any browser, but in mobile/tablet devices  if I have much information it has a delay, kind of lag, when opening the select menu.
  If I change to data-native-menu="true", the mobile/tablet devices are totally fluid but doesn't work on any browser of computer.</p>
  
  <p>Any one have any clue of what could it be? Thanks.</p>
