This application is supposed to demonstrate an issue I have encountered with workbox-window where the registraton will be reported but no messages ever resolve and no events get triggered. You can see this behaviour by clicking the "request version" button, clicking the "deep path" link, reloading and trying again. It will be stuck in "waiting for message" forever
Serviceworker Status is Registered
This should work
This should too but doesn't, when you reload on this page
