Issue saving progress on chapter that are just one page

[UnePouleSDF]

Firstly, thank you for this app :)
And secondly, english is not my first language so sorry for any mistake.

Describe the bug
With some LN that have only one page per chapter, you need to read multiple sub-pages to get to the next chapter. But the sub-pages are not tracked by Kover, so when exiting the book, you just return to the first sub-page of the chapter.

To Reproduce
Steps to reproduce the behavior:

1. Read a book
2. Go to a page that have too much information to fit on one screen (to have multiple sub-pages)
3. Navigate to a sub-page (for example if on page 8, you need to stay between page 8 and 9)
4. Exit
5. See that you came back to the start of the chapter

Expected behavior
I except it to work like kavita where it track where you are in the chapter

Screenshots
Here is a video
I navigate in the chapter 2 which is page 8 of a Novel but the progress isn't tracked.
If i go to chapter 3 which is page 9, the progress is saved.

Smartphone (please complete the following information):

• Device: Fairphone 5
• OS: /e/OS 3.7.
• Version: 0.9.0

Thanks for the detailed report, and no worries, no native english speaker here too :)
Kover does indeed track subpages progress already (which is what triggers the highlighted paragraph on resume, when enabled and successful) and should be compatible with the web UI, so that reading on the browser and switching to Kover should resume to the same point and vice versa. That's the idea at least, but it seems something is definitely broken there. Do you experience that on all LN/EPUB, or just on some?

I tried with another series (epub files). At first it worked like intended.

Then i downloaded it, and sub-page progress was broken. Then I removed the download, but it was still broken until I finished my volume.

Now it does work like intended.
