title: Chrome Vox not getting radio buttons
body: <p>I'm testing a website for accessibility using Chrome Vox. I have 3 radio buttons, one of which is selected. I have no idea why, but Chrome Vox only reads the selected radio button, the others are ignored.</p>
  
  <p>Here's an example:</p>
  
  <pre><code>&lt;p&gt;Chrome Vox test&lt;/p&gt;
  
  &lt;input type="radio" id="radio1" name="radio" tabindex="0" role="radio" aria-checked="false"&gt;
  &lt;label for="radio1" class="space"&gt;Big explosions!!&lt;/label&gt;
  
  &lt;input type="radio" id="radio2" name="radio" tabindex="0" role="radio" aria-checked="true" checked&gt;
  &lt;label for="radio2"&gt;Free beer!!&lt;/label&gt;
  
  &lt;input type="radio" id="radio3" name="radio" tabindex="0" role="radio" aria-checked="false"&gt;
  &lt;label for="radio3"&gt;Hot girls!!&lt;/label&gt;
  </code></pre>
  
  <p>Here's a snippet:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="true">
  <div class="snippet-code snippet-currently-hidden">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;p&gt;Chrome Vox test&lt;/p&gt;
  
  &lt;input type="radio" id="radio1" name="radio" tabindex="0" role="radio" aria-checked="false"&gt;
  &lt;label for="radio1" class="space"&gt;Big explosions!!&lt;/label&gt;
      
  &lt;input type="radio" id="radio2" name="radio" tabindex="0" role="radio" aria-checked="true" checked&gt;
  &lt;label for="radio2"&gt;Free beer!!&lt;/label&gt;
  
  &lt;input type="radio" id="radio3" name="radio" tabindex="0" role="radio" aria-checked="false"&gt;
  &lt;label for="radio3"&gt;Hot girls!!&lt;/label&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Here's a <a href="http://jsfiddle.net/Cthulhu/ma37btye/1/" rel="nofollow">fiddle</a>.</p>
  
  <p>Any ideas of why Chrome Vox ignores the other radio buttons? What can I do to solve this? Thanks.</p>
