Describe the bug
No matter what I do and how simple the card is I try to create. The Icon never shows up. I tried multiple browsers, dashboards, entities etc. Also tried to reinstall Button card.

Name e.g. is shown, icon not. This happens since some weeks.

The same code on another instance of HA works flawlessly

example code:

type: custom:button-card
entity: light.licht_wohnzimmer
show_icon: true

Version of the card
Version: 4.1.2

To Reproduce
This is the configuration I used:

type: custom:button-card
entity: light.licht_wohnzimmer
show_icon: true
