The up/prev/next links are different because we don't want them to
scroll with the text. I.e. we're willing to give up on keyboard-clicking
and copy&pasting to be able to use the header-line.
Maybe we'd want to put the breadcrumbs in the header-line as well, but
that would require 2 lines of header-line and I'm not sure I'd be in
favor of such a change (especially as computer displays tend to get
less and less tall nowadays, for reasons that escape me).

I think it's OK: it is a misfeature, so it's normal for people to
complain about them. Let's not pretend it's a feature when it's not.
Or to reverse your argument: if it looks like a header-line, people will
report bugs about the fact that it doesn't stay at the top of the
display ;-)
I.e. in any case it won't match all the user's expectations and I don't
think this argument will give us a good basis on which to make a decision.

Interesting. That deserves a comment.

Yes, that's better, thank you.
