title: How does ng-selected work?
body: <p>Here is a snippet. Q2 is selected as I expect.</p>
  
  <pre><code>&lt;select name="quarter" ng-model="Quarter" &gt;
      &lt;option value="1" &gt;Q1&lt;/option&gt;
      &lt;option value="2" ng-selected="Quarter=='Q1'"&gt;Q2&lt;/option&gt;
      &lt;option value="3"&gt;Q3&lt;/option&gt;
      &lt;option value="4"&gt;4&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>Changing <code>'Q1'</code> to <code>'Q2</code>' makes nothing as selected as I expect. Now putting <code>ng-selected="Quarter=='Q1'"</code> DOES NOT make Q1 selected until i delete <code>ng-selected="Quarter=='Q2"</code></p>
  
  <p>wtf. How is this suppose to work?</p>
