• Removing the Iris.Cloud.Client project reference may lead to test failures if any tests rely on those types; confirm tests no longer need this reference or update them accordingly.

Commented-out logic prevents the active-state icon from being applied. Either implement the Material Symbols replacement logic or remove the TODO and cleanup this method to avoid confusion.

Suggested change

	//ToDo fix for material symbols
	return Icon; //isActive ? Icon.Replace("rounded", "filled") : Icon;
	return isActive ? Icon.Replace("rounded", "filled") : Icon;
