title: jQuery hide/show a div containing Highcharts
body: <p>I want to <code>hide/show</code> a div that contains highcharts. 
  In chrome and Safari I'm able to successfully hide the div while in Firefox, the imprints of the highcharts get remained. 
  Here is my <a href="http://jsfiddle.net/zkbb4/" rel="nofollow">jsFiddle Link</a>. Try opening this link in Chrome and Firefox.
  How do I hide the highcharts in Firefox?</p>
