advancedSlicerVisual : value fontColor theme setting not applied

[bdarbonneau]

Using the March 2024 version of Power BI Desktop.
I am trying to set the default font color of the button values in the new button slicer visual, but the theme settings are not applied. Setting the font size, family is OK, but the following code does not affect the font color. I have also tried using theme colors, but to no avail. Is this a bug or am I missing something ?

"advancedSlicerVisual": { "*": { "value": [ { "show": true }, { "$id": "default", "fontFamily": "Segoe UI Semibold", "fontColor":{"solid": {"color":"#4A4A4A"}}, "fontSize": 10, "transparency": 0, "horizontalAlignment": "center" }, { "$id": "selected", "fontColor":{"solid": {"color":"#4A4A4A"}} } ] } }

I'm also hitting this issue with the latest theme file, I can't set the fontColor but I can set the other properties for values.
