            Bug ID: 236349
           Summary: Permission API: PermissionStatus with registered
                    "change" listeners shouldn't be GC'd
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

Related spec change:

It should be possible to get a PermissionStatus object, register a listener on it, and allow it to go out of scope (but not have it GC'd) 

For example: 

```JS
(async () => {
  const perm = await navigator.permissions.query({ name: "geolocation" });
  perm.onchange = () => { console.log("pass") };
  console.log("going out of scope");
  // bye bye perm
})();

// prompts for permission
navigator.geolocation.getCurrentPosition(console.log);
```

Changing the permission of Geolocation in the above should produce "pass" in the developer console.
