The following is necessary in case the app_id is set-up at a later point
in time, and it is intended as a work-around for WAM/chromium68 clients
that specify the app_id after the initial surface commit. Note that
activation will not work, in case the application will never set-up an
app_id because we can't identify which app_id to switch to.
The activation phase is needed to inform the client of the window
dimensions, and it is mandated by the XDG-shell protocol.
