[BUG] - Script bleeds through onto homepage

[DarkUFO]

As you can see from the attached screenshot, our poll code is displaying on the article list. All script code should be hidden.

This is the code that is contained within the post

<script>
  (function () {
    var opst = document.createElement('script');
    var os_host = document.location.protocol == "https:" ? "https:" : "http:";
    opst.type = 'text/javascript';
    opst.async = true;
    opst.src = os_host + '//' + 'www.opinionstage.com/polls/2266099/embed.js';
    (document.getElementsByTagName('head')[0] ||
      document.getElementsByTagName('body')[0]).appendChild(opst);
  }());
</script>
