The scroll ran on `rendered` changing, which is the moment the reload STARTS —
frameDoc still pointed at the outgoing document, so it scrolled the page about to
be replaced and the new one arrived at the top. Every write from the editor did
it: reorder a gallery or a partner, lose your place.
It now happens in onDocument, against the document that has just loaded. The
effect stays for the other case — a different band chosen with no reload — and
keeps its smooth scroll, because there you are watching it move.
