FIX: preserve scroll position when returning to user activity streams (#42435)

committed 12:36PM - 07 Aug 26 UTC

Scrolling a user activity stream far enough to trigger infinite scroll, opening …a topic, then pressing back would land the user higher up the page than where they left off. The scroll position was being restored correctly, but the stream was refetched from scratch, so the page only held its first page of items and was too short to scroll back to the saved offset — the browser clamped it. On a back/forward navigation we now reuse the stream we left behind, including everything infinite scroll appended, so the page is the same height it was and the restored position lands where the user was reading. The stream is stored per history entry via the historyStore service, so ordinary forward navigation still loads a fresh stream.
