title: Video files showing up in file input accept=audio attribute
body: <p>I am implementing file upload in my application. I have input elements for different media types.</p>
  
  <pre><code>&lt;label&gt;Audios&lt;input type="file" accept="audio/*"/&gt;&lt;/label&gt;
  &lt;label&gt;Videos&lt;input type="file" accept="video/*"/&gt;&lt;/label&gt;
  </code></pre>
  
  <p>Everything is working fine in Firefox. However, in Chrome webm files are showing up for audio input type. And in IE 3gp files are showing.</p>
  
  <p>Can somebody please explain what's happening here?</p>
