Every course-loading path (Library browser, Continue Watching, Next Up, ...) goes through loadCoursePath(), which reloads the page after POSTing to /load_course - a plain reload never touches history, so once you were on the course view, back had nothing of ours to land on and fell straight through to exiting the app. Push a history entry before that reload, and teach the back handler that popping back to the course view means "unload the course and reload" (there's no client-side way to patch back to the library view's markup - it's a distinct server render tied to current_course). Also restore the exact library folder trail on that reload instead of resetting to the root, so back genuinely returns to where you were browsing, not just the top level.
