Redirection away from and back to route fails to cancel navigation

Steps to reproduce

• Run a long async function within a route guard
• Start at route A, navigate to route B, and then back to A again before the guard for B resolves

What is expected?

Navigation to route B is cancelled, or at least completed and re-routed to route A

What is actually happening?

NavigationDuplicated is thrown, and the page navigates to and stays on route B

This could be technically a breaking change but I don't see a reason to not cancel ongoing navigation when trying to navigate to the same location
