when not in widescreen mode, it's normal for the header to scroll away when the content scrolls, shouldn't be that slow tough. i wonder tough if it should do that only when actually in mobile mode ie running on android or plasma mobile...
I think yes - in mobile mode header should auto hide - and in wide mode - it shouldn't - this is expected.
fixed as well by https://commits.kde.org/kirigami/d37a938f2a13286f629d0a16d0b2efe78ab463d4
