[w3c/ServiceWorker] Allow the service worker to work in the background without stopping for installed PWA (Issue #1728)

### Current situation:
as soon as the page closes or becomes inactive, the browser stops the work of the service worker. The idea is clear - the browser cannot keep all service workers of all pages ever opened in working order

But not so long ago, we had the opportunity to install PWA applications (or add them to the home screen in iOS)! This action transfers a simple page with service worker to the category of installed applications. Native installed applications have the privilege to stay running in the background. 
Why do the installed PWA applications not have this feature!?

### Proposal:
it will allow installed PWA applications to have a service worker running constantly in the background
