title: fullpage.js will only scrollOverflow after window resize
body: <p>I have a fullpage.js site setup <a href="http://fatslug.ca/pnp/" rel="nofollow">here</a>.
  The first section has no scrollOverflow, but the second section is a grid (generated using gridify), which requires (on certain screen sizes), for it to be a scrollable section.</p>
  
  <p>The problem is it refuses to scroll. However, if I resize the window (even by a single pixel in any direction), then the fullpage.js scrollbar will appear for that section.</p>
  
  <p>Does anyone have any idea why fullpage.js is acting this way? And how can I get the scrollbar to appear in that section without having the resize the window manually?</p>
  
  <p>It's worth noting, I've been able to get the same thing working using the fullpage.js example page for scrollOverflow. That is setup right <a href="http://fatslug.ca/fullpage/examples/scrolling.html" rel="nofollow">here</a>. However, I haven't been able to figure out why it works there, but not in my original page!</p>
