Summary: Rotating from portrait to landscape loses position by quite a few pages (sometimes up to 20 pages)

Steps to Reproduce: - Open a book in iBooks (a few externally added EPUBs in this case, other formats not tested)
- Have scroll view enabled instead of pages
- Scroll to some position (or read a few pages)
- Rotate the device to landscape

Expected Results: Ending up at the same position/page before the rotation

Actual Results: Ending up a few pages ahead of the old position, manual scrolling back and finding the current reading position is required

Version: iOS 9.3 (13E234)

Notes: 

Configuration:
- EPUBs externally added (not tested with ebooks bought from the iBooks store)
- Scrolling instead of paging
