View content cleared when reopening app in same browser tab

[danielwiehl]

Describe the bug

The content of path-based peripheral views is cleared when reopening the app in the same browser tab, e.g., via a browser bookmark.

This only happens if hash-bashed routing is enabled: provideRouter(routes, withHashLocation()).

To Reproduce

Steps to reproduce the behavior:

1. Bookmark the application with the trailing hash (e.g., http://localhost:4200/#/)
2. Click the browser bookmark
3. Open a path-based view in the peripheral area
4. Click the browser bookmark to reload the application
5. See that the view content is cleared

Expected behavior

View content is not cleared, and the outlets in the URL are restored.
