Issue: [Go Router] Popping state and re-rendering scaffold at the same time doesn't update the URL on web 
Labels: platform-web,package,has reproducible steps,P2,p: go_router,team-go_router,triaged-go_router,found in release: 3.22,found in release: 3.23

### Steps to reproduce

In the given sample:

1. Press Push on the root screen
2. Press push again on route A
3. Press "Go Back" on screen B

### Expected results

The screen is popped and the URL is updated

### Actual results

The screen is popped and the URL is still `/#/a/b` on web. This only happens if `counterStream.increment();` is called just before popping. If it's omitted, then everything works as expected.
