title: Input button target="_blank" isn't causing the link to load in a new window/tab
body: <p>I have an HTML file with an input button. 
  This is only an example button, but it's including all necessary info of code:  </p>
  
  <pre><code>&lt;input type="button" onClick="parent.location='http://www.facebook.com/'" value="facebook" target="_blank"&gt;
  </code></pre>
  
  <p>For some reason, it's not loading in a new window/tab.</p>
