If the Duo folded while the other tab still showed a detail, that tab's
list came back with an empty title. The navigation item kept its custom
title view, but the bar no longer hosted it.

Screens 5.0.0-t3.32 sets a detached custom title view again once the
screen appears, which makes the bar show it.
