I receive the JavaScript error "Error: Unable to get property 'parentNode' of undefined or null reference" in IE11 when I click on any of the toolbar buttons. This only happens when calling the set_content() method to set the text via JavaScript. The Editor toolbar buttons work fine if I don't use set_content() but unfortunately I have to. Changing the compatibility mode back to IE10 fixes the issue.
