flutter run

If you click on the following, in this sequence:

• The "A Screen" Tab
• The "View A Details" link
• Back navigation arrow
• The "B Screen" Tab
• The "View B Details" link
• Back navigation arrow

Then the only things that are logged are:

[MyNavObserver] didPush: route(: {}), previousRoute= null
[MyNavObserver] didPush: route(/b/details: {}), previousRoute= route(: {})
[MyNavObserver] didPop: route(/b/details: {}), previousRoute= route(: {})

Even though all navigation was through things like GoRouter.of(context).go('/a')

The only route that appears as part NavigatorObserver is the b/details route, and I wonder if it's because it's using a _rootNavigatorKey.
