title: jQuery FullCalendar not rendering
body: <p>I have a working fullcalendar on my site, however, the actual calendar table doesn't show until you change the month/year or select "today". </p>
  
  <p>If I look at the rendered source, I see that the div around the table is empty until I press a button.</p>
  
  <pre><code>&lt;div style="position: absolute; -moz-user-select: none;" class="fc-view fc-view-month fc-grid" unselectable="on"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>Does anyone have a clue why this is happening?</p>
