title: Wordpress - link is being stripped when I post, how to stop?
body: <p>When I try to post this:</p>
  
  <pre><code>&lt;a class="post-handle" href="#" data-timestamp="2.09"&gt;my link&lt;/a&gt;
  </code></pre>
  
  <p>The post ends up as:</p>
  
  <pre><code>&lt;a class="post-handle" href="#"&gt;my link&lt;/a&gt;
  </code></pre>
  
  <p>How can I stop WP from swallowing the <code>data-timestamp="2.16"</code> portion?</p>
