When performing a search and sorting by book, if while on the first page of search results I view a book with multiple pages of search results and so go onto the second page of search results - when I collapse the book again I am left on the second page of search results, even though I haven't viewed the remainder of books on the first page yet. I should be taken back to the previous page so I can keep browsing search results where I left off.
Steps to reproduce:
Search for God (or any other largely prevalent syntax) in basic search sorting by book
Open a book with more than one page of search results
Navigate to the second page of results
Collapse book, to continue looking in another book.
Your now on the second page of search results, but want to be on the first page of search results.
