Comienza reproduciendo el problema en la vista general vinculada del menú de Material en un dispositivo iOS con VoiceOver activado; después, sigue el manejo del foco de mat-menu en el primer y el último elemento del menú. Se considera terminado cuando los deslizamientos hacia delante y hacia atrás mantienen el foco de VoiceOver dentro del menú abierto en lugar de moverlo al elemento siguiente.
