Which @angular/* package(s) are the source of the bug?

router

Is this a regression?

No

Description

According to the Angular documentation, the router.getCurrentNavigation() method should return null once navigation has completed. However, when subscribing to the Router events and listening for the NavigationEnd event, router.getCurrentNavigation() still returns a non-null Navigation object.

Expected Behaviour:
router.getCurrentNavigation() should return null when the NavigationEnd event is emitted.

Actual Behavior:
router.getCurrentNavigation() continues to return a Navigation object even during the NavigationEnd event.
