ServiceWorkerGlobalScope: notificationclose event

The notificationclose event fires when a user closes a displayed notification spawned by ServiceWorkerRegistration.showNotification().

Notifications created on the main thread or in workers which aren't service workers using the Notification() constructor will instead receive a close event on the Notification object itself.

Note: Trying to create a notification inside the ServiceWorkerGlobalScope using the Notification() constructor will throw an error.

This event is not cancelable and does not bubble.
