In book, when editing mode is on, the parameters from the URL dissapear

Steps to reproduce

1. Login as admin.
2. Create a course and add a book with a chapter.
3. Go to the main course page.
4. Turn editing mode off.
5. Access to the book.
6. Check the URL is something like "mod/book/view.php?id=xxx".
7. Click the Turn editing on button.

Expected behaviour

The URL preserves all the parameters (so it keeps being "mod/book/view.php?id=xxx").

Current behaviour

The URL is set to mod/book/view.php

Although I don't think this is causing some issue right now, I've faced it might fail once MDL-71956 lands.
