Keep the message list visible and focused while a chat loads

Opening a chat whose history was not loaded yet hid the scroll area
and parked keyboard focus on the unnamed HistoryWidget container until
the first messages arrived, so screen readers announced it as a bare
"grouping" for the whole load.

Keep the scroll visible during the first load for everyone, like the
newer sections do: the empty message list takes focus right away and
the container-parking branch goes away entirely. With a screen reader
the list announces the focused message once the first slice of
messages arrives, the same as when opening an already loaded chat.
