Book reader Table of Contents loses active section

[KobraKid]

What happened?

I have an EPUB which has a TOC like the following:

<navMap>
  ...
  <navPoint>
    <text>Chapter 1</text>
    <content src="Text/section-0013.html"/>
  </navPoint>
  <navPoint>
    <text>Chapter 2</text>
    <content src="Text/section-0020.html"/>
  </navPoint>
  ...
</navMap>

However, the EPUB has files for section-0014.html, section-0015.html, etc.

In Calibre, the TOC keeps "Chapter 1" highlighted while I'm in any of section-0013.html through section-0019.html. But in Kavita, as soon as I scroll past section-0013.html there is no "active" chapter in the TOC until I reach section-0020.html.

In the screenshots, you can see that when on the last page of section 11, the first chapter of the book is bolded in the TOC. But on the first page of section 12, there is no longer a bolded section in the TOC. It's not until I reach section 22 that the next chapter is bolded in the TOC.

What did you expect?

I would expect Kavita to keep the title of chapter 1 bolded until I reached the beginning of chapter 2. I don't think there should be a case where there is no active chapter.
