- Make the chapters button appear consistently.
- Previously, it was only appearing for Original.
- We still hide it for mobile, as per previous explanation.
- Changed the Chapters button position and popup aesthetics.
- Deemed not useful in mobile, unless you have an S-pen that can hover.
- The chapters button (that invokes the chapters popup) would make more sense in Mobile, but we need to deal with the limited controlbar space first (e.g. overflow menu system)
