"the radio option is active" would 'selected' be better than 'active' here?

|hovered| indicates highlight, right? How does it describe selection?

I avoided the word selection because it's ambiguous here (it's used for both a
"checked" radio button and a mouse hover, depending on context).

+// state, and |default_icon_color| is the base color that should be used for
+// the icon (which may be ignored based on the other two flags).
