title: Font scaling Chrome not working
body: <p>Given this CSS</p>
  
  <pre><code>body {
      font-size: 62.5%;
      font-family: Arial,sans-serif;
      line-height: 2em;
      color:#333
  }
  
  .post_text p {
      font-size: 1.2em
  }
  </code></pre>
  
  <p>why doesn't text in <code>.post_text p</code> scale on Chrome when I click Ctrl-+?</p>
  
  <p>It does behave correctly on Firefox.</p>
