Demo is broken

[mocanuga]

The demo is broken in Edge/17.17134
It seems that the whole service worker registration process is broken.

(function (win, nav) {
    'use strict';
    var pushNotificationsSupport = 'serviceWorker' in nav && 'PushManager' in win && 'Notification' in win;
    console.log('push notification suppport: ', pushNotificationsSupport)
    if(pushNotificationsSupport) {
	nav.serviceWorker.register('/tests/ie/sw.js', {scope: '/tests/ie/'})
		.then(function() {
			console.log(arguments);
		})
		.catch(function(err) {
			console.log(err);
		})
    }
}(window, navigator));

The code above fails with
{description: "Invalid argument", message: "Invalid argument", number: -2147418113}

I came here to report that the demo is still broken as of Jan 27th 2023.
I tried https://webpushdemo.azurewebsites.net/ on macOS 13.2 with Firefox 109, Chromium 110 and Safari 16.3. Subscribing seems to work, but after closing the tab and waiting for the popup notification, it never arrives.
