When loading a Book from a custom link, the section-id is not passed as a URL parameter.

Steps to Recreate:

1. Create a course with Topics Format and 3 or 4 sections.
2. Add book activity to a section.
3. Ensure that the book have at least two chapters.
4. Create a URL activity in the general section.
   • Use the link to the section id as the link input for URL Activity.
   • E.g site/course/view.php?id=4&section=1
5. Navigate back to the course and turn editing off.
6. Click on the link to the section.
7. Click on the book, we can see section id being passed as parameter.
8. Navigate through book. The section id is omitted.

If the section-id would have passed then the link for section in breadcrumb would lead to the section page as opposed to pointing the section tab in course page.

ie. we get view.php?id=4#section-1 instead of view.php?id=4&section=1
