The UP NEXT card kept pointing at this morning's first stop hours after it had started, and at day one of a trip that ended last month. A header promising what comes next, sitting above something that is over. It now stays away on a day that has passed and once today's timed plan has run out — a day whose stops carry no times at all still shows its first stop, there is nothing stale about that. The timeline card already collapses the reserved space when there is no up-next, so the layout closes cleanly. Seeding the plan day also lands on the next day still ahead when today falls into a gap in the dates, instead of dropping back to day one. A trip that is already over keeps opening on its first day. And a day that was selected before the shell mounted now counts as seeded, so clearing the selection is left alone instead of being re-seeded on the next render — which is what the guard was there for in the first place. Based on #2055.
