[BUG] AniList tracking not updating in horizontal double page reader mode

[ghtjason]

Describe the bug In horizontal double page reader mode, reading until the end of a latest chapter with an even number of pages (e.g. 18) displays as being on the second-to-last page (e.g. 17 of 18). Because it technically never reaches the last page of the chapter, AniList tracking (and I assume other trackers as well) is never updated. Progress updating works as expected if I switch to vertical mode and scroll to the final page.

To Reproduce

1. Start tracking a manga (e.g. Chainsaw Man) through AniList.
2. Read the latest chapter (e.g. chapter 137) in horizontal double page reader mode until the final double page.
3. AniList fails to update.

Expected behaviour AniList should update when I reach the final two pages of the chapter in horizontal double page reader mode, even if the bottom right displays 17 of 18.

App Version 0.8.3
