title: @import CSS not working
body: <p>I am using the <a href="http://chargify.com" rel="nofollow noreferrer">Chargify</a> service and within their settings they allow you to include some custom CSS. I am including</p>
  
  <pre><code>@import url(http://swag-box.herokuapp.com/chargify.css);
  </code></pre>
  
  <p>I can see that the CSS is being embedded into the page but It doesn't seem to be affecting the page in anyway.</p>

  <p>You can view the live page <a href="https://swagbox.chargify.com/h/3344970/subscriptions/new" rel="nofollow noreferrer">here</a>.</p>
  
  <p>What exactly is the problem here?</p>
