Expected behavior

Clicking your browser's "back" button from the Discussion tab should take you to the previous page.

Steps to reproduce

1. Start on any course page, such as https://apps.redwood.demo.edly.io/learning/course/course-v1:HinaX+HX101+2024_T2/home
2. Click on "Discussion".
3. Use your browser's back button.
4. Witness a brief moment of "All posts sorted by recent activity" on the left.

The URL changes briefly from
https://apps.redwood.demo.edly.io/discussions/course-v1:HinaX+HX101+2024_T2/posts
to
https://apps.redwood.demo.edly.io/discussions/course-v1:HinaX+HX101+2024_T2/
and then back to
https://apps.redwood.demo.edly.io/discussions/course-v1:HinaX+HX101+2024_T2/posts

The original issue was reported on the BTR board as part of the redwood testing effort: openedx/wg-build-test-release#346
