title: Data Icon not working in Safari
body: <p>I'm trying to turn Data Icons into navigation. The icons are clickable in Firefox and Chrome, but they are not clickable in Safari. Thanks for your help! Here's my mark-up:</p>
  
  <pre><code>&lt;a href="#"&gt;&lt;span data-icon="!" aria-hidden="true" class="close"&gt;&lt;/span&gt;&lt;/a&gt;
  </code></pre>
