Navigate back via history

[ccremer]

Summary

This should give a greater UX since whenever the user clicks the close button, they expect to be taken where they come from, and not to the relative parent page. Especially if linked from another component entirely.

(Inspired by https://nils-mehlhorn.de/posts/angular-navigate-back-previous-page/)
