title: jQuery event contextmenu triggers underlaying div
body: <p>looking at this event (being bind on 2 divs overlapping each other, look at the jsfiddle)</p>
  
  <pre><code>.on('contextmenu', function() { ... });
  </code></pre>
  
  <ol>
  <li>Why do <em>both</em> divs being triggered?</li>
  <li>How can I detect this and or stop the underlaying div from triggering?</li>
  </ol>
