title: Frame load interrupted when downloading excel files
body: <p>I have an Angular script which goes to my server and grabs some data. The call looks like the following:</p>
  
  <pre><code>    $http.post(url).success(function(response) {
          // Do some work...
  
          // Go to the link that the server provided
          window.location.href = response.link;
      });
  </code></pre>
  
  <p>So the user will then be redirected to download the file (the file is hosted on S3). The file downloading and everything works...but in Safari I get the following in my console:</p>
  
  <pre><code>Failed to load resource: Frame load interrupted
  </code></pre>
  
  <p>This is despite the fact that the file was downloaded <strong>successfully</strong>! Is there anything i'm missing here? No other browser has this error, however, even in Safari, the file downloads and I still get the error.</p>
