A smooth scroll to the bottom from far up reports a distance above the
pin threshold on its way down. The scroll handler read that as the reader
scrolling up and unpinned the thread, so the new message and the answer
that streamed in after it stayed out of view.
Only a move up unpins the thread now. A reader who scrolls up while an
answer streams is still left where they are.
