show_state: true not working?

[criticallimit]

Hi,

I´m using the button instead of a switch. But normally the icon is changing color when activated.
This is not working. Would be helpful to see when the cooker is activ, specially when you have several buttons in a row to see which profil is activated

type: button
tap_action:
action: call-service
service: xiaomi_miio_cooker.start
service_data:
profile:0001E10100000000000.....
show_icon: true
show_name: true
icon: mdi:rice
name: Tasty Reis
icon_height: 40px
show_state: true
