Seems like a behavior the router should be responsible for. e.g., navigate to
"the previous route", whatever it was, with a fallback of Basic.

Since this is a navigable route... history.back() could go back to before
Settings.

Done.

Yes you are absolutely correct here. I realized the desired behavior is the same
as settings-subpage.

If there is no previous route, it goes to Advanced.
