title: jquery remove "selected" attribute of option?
body: <p>Why doesn't this work in IE8 to deselect all options in a multiline selectbox?</p>
  
  <pre><code>$("#myselect").children().removeAttr("selected");
  </code></pre>
  
  <p>Is there a workaround? Nothing I could think of (attr("selected","") etc) seems to work.</p>
  
  <p>UPDATE: <a href="http://jsfiddle.net/UFk5w/21/" rel="noreferrer">Here is an updated jsFiddle.</a> I have <em>at least</em> got it to degrade so that in IE8 the first option is selected. But without the hardcoded selected='selected' <em>and</em> the .attr call that IE8 seems to need, it does 3 different things in Firefox, Chrome and IE8! <a href="http://jsfiddle.net/UFk5w/23/" rel="noreferrer">See this version:</a>, which is simple and seems like it should work:</p>
  
  <ul>
  <li>in Firefox: nothing selected </li>
  <li>in Chrome: 0th option selected</li>
  <li>in IE8: 1st option selected</li>
  </ul>
  
  <p>Maybe I have made myself crazy and there is a mistake in there somewhere I can't see?</p>
