title: Mailchimp repeatable blocks issue
body: <p>I have next table in my template:</p>
  
  <pre><code>&lt;table ...&gt;
      &lt;tr mc:repeatable mc:hideable&gt;
          &lt;td mc:edit="mc-news-item-image"&gt;&lt;a href="#"&gt;&lt;img .../&gt;&lt;/a&gt;&lt;/td&gt;
          &lt;td mc:edit="mc-news-item-h3"&gt;&lt;h3&gt;Lorem ipsum.&lt;/h3&gt;&lt;/td&gt;
          &lt;td mc:edit="mc-news-item-date"&gt;&lt;span&gt;22.10.13&lt;/span&gt;&lt;/td&gt;
      &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>In edit campaign mode if I try to dublicate a row I get copy of it but can't edit any block in template. Any help would be much appreciated!</p>
