title: Safari Popup Does Not Open - Not Returning Object when Executing window.open()
body: <p>Given the method:</p>
  
  <pre><code>function openInNewWindow(url) {
      var win = window.open(url, "title");
      win.focus();
  }
  </code></pre>
  
  <p>In Safari the object "win" is "undefined" after "window.open" and the new window is not opened.</p>
  
  <p>Any ideas why this happens?</p>
