title: on $(document).foundation(); Uncaught TypeError: Cannot read property 'top' of undefined
body: <p>I'm using several foundation plugins on this page. Equalizer, and Reveal. When the foundation initializer is being called it throws <code>Uncaught TypeError: Cannot read property 'top' of undefined</code> on the <code>&lt;script&gt;$(document).foundation();&lt;/script&gt;</code> call.</p>
  
  <p>I assume it's related to the markup being parsed associated to one of the plugins. Here's the markup...</p>
  
  <p>Equalizer...</p>
  
  <pre><code>   &lt;div class="row" data-equalizer&gt;
                  &lt;div class="overlay large-4 large-offset-4 columns clearfix"&gt;
                     ... text
                  &lt;/div&gt;
                  &lt;div class="large-4 columns clearfix"&gt;
                  ... text
                  &lt;/div&gt;
     &lt;/div&gt;
  </code></pre>
  
  <p>Reveal...</p>
  
  <pre><code>&lt;a id="terms" href="terms.php" data-reveal-id="termsModal" target="_blank" data-reveal-ajax="terms.php"&gt;Terms &amp;amp; Conditions&lt;/a&gt;&lt;/label&gt;
  </code></pre>
