A background tab the browser suspended past the record lifetime can have
its writes adopted elsewhere, like a back-forward cache page: shown
again, it now checks resumed() and reloads instead of sending them.
Conflict replays appended a newly viewed item at the end of the history,
where the next 50-item cut dropped it; a replayed recently viewed list is
now kept newest first.
isFavorite() waits for the first user-data read like the list reads, so
a detail page opened during a slow first read does not toggle an
existing favorite the wrong way. A parked backup restore replayed when
the playlist opens waits too, and stays parked while no read succeeded.
