loader.js: Still apply some accessibility changes..

..if a renderHook discards an autorefresh. There is
unfortunately no way to distinguish between a renderHook
that really discards changes or one that applies them
on the DOM itself. If it's the first, this change
*shouldn't* hurt. If it's the latter, users should
benefit.
