Foundation - Off Canvas Scroll Issue

Question

I'm starting with Foundation and trying to get an off canvas example working. I've been struggling because the menu opens and closes like it should, however if the page content is long and you scroll toward the bottom, when you open the menu, the focus is where you are on the page. IE, the fixed toolbar and menu aren't fixed when open.

I've done an example on a fiddle, and would love some help!

JSFiddle Example

HTML

<div class="off-canvas-wrap" data-offcanvas="">
  <div class="inner-wrap">
<div class="fixed">
<nav class="tab-bar">
  <section class="left-small">
    <a class="left-off-canvas-toggle menu-icon" href="#"><span></span></a>
  </section>

  <section class="middle tab-bar-section">
    <h1 class="title">Forest School - PARS Insight</h1>
  </section>
</nav>
  </div>

<aside class="left-off-canvas-menu">
  <ul class="off-canvas-list">
    <li><label>General</label></li>
    <li><a href="#">Snapshot</a></li>
    <li><a href="#">Timetable</a></li>
    <li><a href="#">Homework</a></li>
  </ul>
</aside>

CSS

}

.off-canvas-wrap{  
    height: 100%;
    overflow-y: auto;
}

Javascript
