title: Font precendence issue
body: <p>I have the following CSS line:</p>
  
  <pre><code>font: 700 0.8rem Verdun, Arial, Helvetica, sans-serif;
  </code></pre>
  
  <p>Arial is chosen, and not until Verdun is loaded;</p>
  
  <p>If I use:</p>
  
  <pre><code>font: 700 0.8rem Verdun;
  </code></pre>
  
  <p>Verdun font is loaded, immediately, so there is no broken path.</p>
  
  <p>I want Arial to be used only if Verdun is not found;</p>
