🐞 bug report

Affected Package

Is this a regression?

Dont know

Description

When using Router.navigate and passing a relative route in NavigationExtras, navigation silently fails unless the relative route is CURRENTLY active. Documentation does not state that relativeTo route must currently be active (though the class type is called ActivatedRoute), that restriction would seem to be unwanted, and in any event a silent failure to navigate is certainly not expected behavior.

🔬 Minimal Reproduction

https://github.com/slubowsky/router-test

1. Run app.
2. Navigate to one by clicking the "one" button. This sets up a navigation function in NavigationService to perform navigation when called.
3. Click "Go to three using navigation service" button. The navigation function is called and app successfully navigates as expected.
4. Navigate to two by clicking the "two" button.
5. Click "Go to three using navigation service" button. The same navigation function that previously successfully navigated is called again but this time app silently fails to navigate.
