hdy_expander_row_set_show_enable_switch not working properly

hdy_expander_row_set_show_enable_switch does not work when row is created manually without glade:

#include <gtk/gtk.h>

#define HANDY_USE_UNSTABLE_API
#include <handy.h>

int main (int argc, char **argv) {
  GtkWidget *window;
  GtkWidget *row;

  gtk_init (&argc, &argv);
  window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
  row = GTK_WIDGET (hdy_expander_row_new ());
  hdy_action_row_set_title (HDY_ACTION_ROW (row), "Switch test");
  hdy_expander_row_set_show_enable_switch (HDY_EXPANDER_ROW (row), FALSE);
  gtk_container_add (GTK_CONTAINER (window), row);

  gtk_widget_show_all (window);
  gtk_main ();

  return 0;
}
