            Bug ID: 283803
           Summary: Inconsistent Behaviuor of `navigator.permissions` API
                    on Safari iOS
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

I'm working on implementing a PWA and I noticed a few issues that are specific to Safari, and more so to Safari on iOS (https://developer.apple.com/forums/thread/769794). One of those is that the `navigator.permissions` API misbehaves in two ways:

1. On iOS (but apparently not on desktop), `navigator.permissions.query({ name: 'notifications' })` always returns 'prompt' regardless of the actual permission value, and even if the notification permission was requested in that same session. However, `Notification.permission` does return the correct value. This behaviour is inconsistent with other browsers, that return consistent values no matter how permissions are queried.
2. Perhaps related to the first issue: a `change` listener on the permissions result object form `navigator.permissions.query` never gets triggered.

I've created a simple HTML app to demonstrate this issue, which I attached.
