One screen brought to front inside the user session, with when it came to
front: the app's foreground surface trail (the app_session_navigation of
the 451 feed/timeline block, and the source of that block's
container-module history). It is not the navigation chain: the 451 launch
restarts the chain at the feed while the trail keeps the prompt shown before
it ([save-credentials, feed_timeline]). Kept only inside a session; a
new session starts an empty trail.
