The MOBI6.init() method builds #fileposList (the map of all filepos byte-offset references, used to insert <a id="fileposXXXX"> anchors into section HTML) after calling getGuide() and the TOC-section loader — both of which call createDocument() → loadText(), which caches the section HTML. Since #fileposList is still empty at that point, the cached HTML has no anchor elements.
Later, when Foliate calls getElementById('filepos12345') on the cached (anchor-less) document, it returns null, so the paginator falls back to ?? 0 — i.e. scroll to position 0 = first page.
For EPUB this doesn't happen because chapters are separate files; navigation loads a new section by index, not by searching for an anchor element within one section.

The XHTML 1.1 spec says
The start tag of the root element of the document MUST explicitly
contain an xmlns declaration for the XHTML namespace
There doesn't seem to be such a requirement in the WHATWG spec. But at
any rate browsers won't render it properly without the XHTML namespace.
- KindleUnpack's rules for when to insert the coverpage seems a bit
too involved to replicate exactly.
- The feature is marked "XXX experimental" in KindleUnpack source code
after 10 years.
- The feature makes no sense as the cover page might not even exist in
the source EPUB in the first place.
It seems to me now that it might be better to just bite the bullet.
