javascript - Firefox の CSS アニメーションが機能しない?

Question

パスのようなメニューhttp://jsfiddle.net/U7cjj/1/を確認し、オレンジ色のボタンをクリックして、メニューがファンアウトするのを確認します。この効果は、jQuery と CSS アニメーションを使用してクラスを切り替えることによって実現されます。

デモは Webkit ベースのブラウザーで動作しますが、Firefox では動作しません。クラスはクリックで適切に切り替えられますが、メニュー項目は表示されません。Firefox はこのタイプの CSS アニメーションをサポートしていませんか? polyfill または Javascript/jQuery フォールバックを使用して機能させる方法はありますか?
