Apple Books no longer highlights the current chapter in Table of Contents on iOS/iPadOS/macOS 27

After updating to iOS/iPadOS 27, Apple Books no longer highlights or scrolls to the chapter I am currently reading when I open the Table of Contents.

Previously, opening the TOC would immediately show where I was in the book. Now I have to manually look through the chapter list to find my current position.

This is especially disruptive when reading long nonfiction books, since I often open the TOC to check my progress and see what is coming next.

I already reported this during the iOS/iPadOS 27 beta, but the issue is still present in the public release.

Has anyone else seen the same behavior?
