title: Serializing fieldset using jQuery in IE11 not working
body: <p>I want to serialize a fieldset. It works fine in Chrome but in IE11 the <code>$myFieldset.serialize()</code> returns an empty string.</p>
  
  <p>I prepared a small fiddle to demonstrate the problem:
  <a href="https://jsfiddle.net/7ayudwok/2/" rel="nofollow">https://jsfiddle.net/7ayudwok/2/</a></p>
  
  <p>If you open it in chrome ir works but not in IE11.</p>
  
  <p>Is there a way to solve this? Or any workaround?</p>
