That code works, you're just looking at an older revision of the MediaWiki page. Since then we've removed the code as the comment lock was only temporary. It would be added to MediaWiki:Wikia.js. Additionally, you can't expect changes to MediaWiki pages to take immediate effect. Wikia uses quite a few methods of caching other than client-side caching. You need to allow time for caches to update.
