When a widget is using the new tinted mode in iOS 18 the Weather app shows the SF Symbols in both white and the tint color. For example, a tinted sun with a white arrow for sunrise.
I can't figure out how to do this. If I add widgetAccentable to the Image(systemName:) the entire Image becomes the tint color.
If I don't use it no combination of rendering mode or foreground style makes the tint color appear.
I can't find any mention of this in the WWDC sessions.
