Five journeys the control has to get right: nothing offered at the root
in either direction, walking both ways with the availability changing
as it goes, reaching the detail view a tab click left behind (which is
the report), the forward list being dropped when the user navigates
from the middle, and the control standing down below 900px.
The first fails on the build before the launch entry was fixed --
enabled, and doing nothing when pressed. It is the assertion that pins
that defect, which otherwise has no visible symptom on desktop at all.
