> +      be done by the user clicking outside the surface, using the keyboard,
> +      or even locking the screen through closing the lid or a timeout.
> +
> +      When the popup is dismissed, a popup_done event will be sent out,

> +
> +      Clients will receive events for all their surfaces during this
