Comment (by dannydehaan):

 This is because getElementsByClassName is only available in HTML5. IE8
 only partially supports HTML5, getElementsByClassName is not supported as
 you can see here. I've made a patch for this. When getElementsByClassName
 is available, the script will use that, otherwise it will use the fallback
 document.querySelectorAll('.wp-editor-wrap');
