Which @angular/* package(s) are the source of the bug?

service-worker

Is this a regression?

No

Description

The messages Observable from SwPush doesn't seem to emit anything when using Push API on iOS. The notifications are correctly set up (and they work) but comparing Windows, Android and iOS side by side shows that only iOS doesn't receive updates on SwPush.messages.
SwPush.notificationClicks does work but only when the app is closed and you swipe right on the notification to activate the "open" option. Tapping on the notification (or swiping right) while the client app is actively running doesn't make notificationClicks to emit.
