           Summary: The onchange event in navigator.permissions.query
                    doesn't work properly in Safari 16.4.
           Product: WebKit
           Version: Safari 16
          Hardware: Unspecified
                OS: iOS 16

# Steps to Reproduce:

1. Open a web page in Safari 16.4.
2. Try to register the onchange event with the following code:
```
navigator.permissions.query({ name: 'notifications' }).then(permissionStatus => {
  permissionStatus.onchange = () => {
    console.log('Notification permission status has changed:', permissionStatus.state);
  };
});
```
3. Choose to either allow or block the notification permission in the popped-up permission request dialog.
4. Observe if the console outputs a message indicating the change of notification permission status.

# Expected Results:

The console should output a message indicating the change of notification permission status when the permission status is changed.

# Actual Results:

The console doesn't output any message indicating the change of notification permission status when the permission status is changed.

# Version Information:

Safari browser version: 16.4
Operating system: macOS Big Sur 11.6.3

# Additional Information:

The onchange event works fine in other modern browsers such as Chrome, Firefox, and Edge.
