Xdg-shell surface doesn't become keyboard active in ivi-shell.

In ivi-shell, keyboard is not active for surfaces created with xdg-shell. I confirmed with hmi-controller and wayland-ivi-extension. I seems that this is because whether the surface was created with the ivi-application protocol is checked in activate_binding().

static struct ivi_shell_surface *
get_ivi_shell_surface(struct weston_surface *surface)
{
        struct ivi_shell_surface *shsurf;

        if (surface->committed != ivi_shell_surface_committed)    //<-- here
                return NULL;

        shsurf = surface->committed_private;
        assert(shsurf);
        assert(shsurf->surface == surface);

        return shsurf;
}
...
static void
activate_binding(struct weston_seat *seat,
                 struct weston_view *focus_view)
{
        struct weston_surface *focus = focus_view->surface;
        struct weston_surface *main_surface =
                weston_surface_get_main_surface(focus);

        if (get_ivi_shell_surface(main_surface) == NULL)    //<-- here
                return;

        weston_seat_set_keyboard_focus(seat, focus);
}

Is there a reason for this?
