This container doesn't seem to show above the login screen.

Thanks for catching this!

I have added a new container with priority CP_LOGIN_SCREEN_SYSTEM_MODAL
Eventually, we will want to pick the appropriate container based on whether the
user has logged in. However, I am leaving that for later

     background_controller_.reset(
         new BackgroundController(background_container_));
   }
