I think we should add a limit to this array (like 10 items or so)

What would be the motivation for it?
Adding a limit would have a few consequences. Let's say the limit is 10 — it means that, when we navigate to the 11th location, we would either:
- prevent any further navigation (since the stack is full). This approach doesn't seem very viable in terms of UX, since it would suddenly prevent the user from navigating to another screen. OR
- drop the initial root location, and make the second location in the array the new "root". This would introduce further complexity in the code (shifting the array, re-setting the
isInitialprop, ...) and it would also mean that the user wouldn't be able to navigate back all the way to the initial route.
I personally think that, rather than enforcing a hard limit on the array, we should tackle this potential issue by making sure that our UIs are not designed to require too many levels of "screen nesting" in the first place.

Hey @youknowriad , do you have any additional thoughts on my previous answer?

Sorry I didn't reply here. I was just thinking about memory leaks but as you said, it might not grow much so fine by me.

That's fine, thank you!

Description
Following the conversation in #37063 and the exploratory work done in #37223, this PR is the first step towards adding support for advanced focus restoration in
Navigator. The plan is to have the work split across 3 PRs:NavigationLinkandNavigationBackLinkcomponents (future PR)This PR adds a basic implementation of location history to the
Navigatorcomponent.Navigatorcomponent, especially the shape of the context object: it now exposeslocation(the current location),push(used to navigate to a new location), andpop(used to navigate to the previous location)How has this been tested?
