Returning to hidden series from "all descriptions" fails

[BWindey]

For exercise-series, there is an option to "Show all learning activity descriptions":

Clicking this you get to a page with the link: "https://dodona.be/en/series/<SERIES_ID>/overview/?token=&user_id=<USER_ID>"
At the top of this page, in the light-blue "menu"-bar, there is an indication on what you are currently viewing, and each thing is clickable to return to that specific thing:

The issue appears when you want to go back to the hidden exercise-series. Clicking on it in the blue menu-bar does not take you back to that series, but instead to the course-page (with all its non-hidden exercise-series).
I would think that it doesn't use the access-token to go back to that series, so it doesn't have permission to view it, and thus returns to the course page.
This could be a bug introduced by pr "Require valid token to view series activities" #5249 .
