* Call the parent constructor.
* Add CSS class to the widget's existing $element, rather than
creating a new one. Doesn't really change anything, just looks

* Prevent the realtimepreview module loading on anything

Because the DOM and layout changes reset the scroll position of the
editing text area, it must be manually saved before enabling/disabling
and reset afterwards.
