title: Adding showinfo=0 to youtube iframe doesn't always work
body: <p>I'm using the following code to add the Youtube video to the website (with showinfo=0 parameter):</p>
  
  <pre><code>&lt;iframe width="560" height="315" src="https://www.youtube.com/embed/qTLOQCSwMpM?rel=0&amp;controls=0&amp;showinfo=0" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>showinfo=0 does successfully remove the top panel with share &amp; watch later buttons <strong>in most browsers, but not everywhere</strong>.</p>
  
  <p>I noticed that on Chrome 62.0.3202.94 on Windows 10 it's still showing that panel:

  <p>How do I get rid of it on all browsers?</p>
