Material icon solar_power doesn't show

Setup, Configuration and Use Widgets

Hi,

I want to use the Material icon solar_power in an widget but it somehow doesn’t show up.
Here is the code of my widget:

uid: widget_PV_expandable
tags: []
props:
  parameters: []
  parameterGroups: []
timestamp: Feb 17, 2023, 12:08:34 PM
component: f7-card
config:
  backdrop: true
  class:
    - card-expandable-animate-width
  expandable: true
  style:
    height: 100px
    width: auto
  swipeToClose: true
slots:
  default:
    - component: oh-button
      config:
        class:
          - cell-open-button
          - card-opened-fade-out
        color: black
        iconMaterial: solar_power
        iconSize: 30px
        style:
          padding-bottom: 35px
          padding-top: 10px
          position: absolute
          right: 0
          top: 0
          z-index: 999
    - component: f7-card-content
...

When I try the power icon for example it works, also a number of other icons, but solar_power (or wind_power) doesn’t show.
What am I doing wrong here?

Unless something has changed, isn’t the parameter just icon and the icon value supposed to be material:solar_power?

In the component reference it says iconMaterial:. And actually on then it works when I try other icons. As mentioned above when I try iconMaterial: power I get the power icon. It only doesn’t work with the solar_power icon.
