> This happens when a service/host component is running, but stop fails. This
> leaves the desired_state in the INSTALLED (i.e., STOPPED) state, while the
> live state is STARTED.
> Currently, UI assumes when desired_state==INSTALLED and state==STARTED, it is
> STARTING. This was a trick to get around the problem of backend live state
> update lagging and to make UI more responsive.
