title: Fancybox + Flexslider only works if content not initially hidden
body: <p>I'm wondering if anyone can shed some light on why this isn't working for me. I'm trying to get a Flexslider gallery working within a Fancybox lightbox. Everything works until I try hiding the gallery content on initial load.  I've put together a simple fiddle (<a href="http://jsfiddle.net/skube/THyYe/1/" rel="nofollow">http://jsfiddle.net/skube/THyYe/1/</a>) to illustrate. Everything works (aside from initially showing the gallery content). When I uncomment the following line in CSS to hide the gallery, and re-run, it breaks.</p>
  
  <pre><code>/* #gallery {display: none;}  uncomment to see not working */
  </code></pre>
