Brief summary

It seems like some series will have their final chapter end with a short "credit" page that doesn't fill the screen, so even when scrolled to the bottom the 2nd to last page is still showing at the top. This seems to cause Kotatsu to think the user stopped on the 2nd to last page instead of the last, and this not show a checkmark for 100% progress for the title.

The only workaround is never to use webtoon mode, but that doesn't work well for some titles that are really designed for that mode.

Steps to reproduce

Search for titles with the "long strip" tag on mangadex.
Look for a title that's not very long (few / short chapters) so rounding up to 100% doesn't happen.
Make sure you are in webtoon scrolling mode (usually detected, not always).
Jump to the last chapter and scroll to the end.

Expected:

You should always get a 100% progress checkmark if you scroll to the very end.

Observed:

It works with some series, especially if they have a full height last page or are are very long overall, but for a few series you will end up with 99% or 98% etc.

It is very hard to specify an exact series to use with this, because as new chapters are added the behavior may change, and the problem will recur temporarily with other seires later.

I have searched the existing issues and this is a new ticket, NOT a duplicate or related to another open issue.
If this is an issue with a parser, I should be opening an issue in the parsers repository.
