title: dropzonejs: acceptedFiles: "video/* doesn't accept m4v in Safari
body: <p>I'm using a dropzone with the option</p>
  <pre><code>acceptedFiles: &quot;video/*&quot;
  </code></pre>
  <p>In Safari, when I click it, I can't select .m4v-files (works in FireFox) in the Explorer-window. However, it works via drag &amp; drop.</p>
