title: jvectormap: NS_ERROR_FAILURE on firefox
body: <p>I use jVectorMap (jquery-jvectormap-2.0.3.min.js)</p>
  
  <p>And I try to display the map: jquery-jvectormap-fr-merc.js as follow:</p>
  
  <pre><code>$('#france_regions').vectorMap({
      map: 'fr_merc'
  });
  </code></pre>
  
  <p>But I got on Firefox:</p>
  
  <pre><code>NS_ERROR_FAILURE: 
  </code></pre>
  
  <p>It seems it because I set the map on a hidden (jquery hide() function) element.</p>
  
  <p>Is there any other way to set the map without render it each time $('#france_regions') become visible ?</p>
