title: Favicon does not show up when doing window.open() in Google Chrome
body: <p>In Google Chrome, when I create a new tab using the JavaScript function <code>window.open()</code>, and then add a favicon, the new tab created does not display the favicon.</p>
  
  <p>Here is a code sample that reproduces the error:</p>
  
  <pre><code>var w = window.open();
  var link = w.document.createElement('link');
  link.id = 'fav';
  link.rel = 'icon';
  link.type = 'image/x-icon';
  link.href = 'https://cdn.sstatic.net/Sites/stackoverflow/img/favicon.ico';
  w.document.head.appendChild(link);
  </code></pre>
  
  <p>The favicon is displayed in Firefox but not in Chrome (tested with Chrome 58). </p>
  
  <p>(To test the sample code, authorize the browser to open new popups)</p>
  
  <p>How can I make it work? Is it the expected Chrome behavior or a bug? </p>
