Even if you only have one tab open to the demo, refreshing the page isn't enough to let the new version take over. This is due to how browser navigations work. When you navigate, the current page doesn't go away until the response headers have been received, and even then the current page may stay if the response has a Content-Disposition header. Because of this overlap, the current service worker is always controlling a client during a refresh. To get the update, close or navigate away from all tabs using the current service worker. Then, when you navigate to the demo again, you should see the horse.
