We are about to make list panels scroll their selection into view automatically. Page up and down are one of the few places that manage the scroll position themselves, keeping the selection at the edge of the viewport rather than in its middle, and nothing covers that today. Asserting on it needs an exact scroll position assertion; only OriginYAtLeast existed so far. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
