[SwiftUI] [Mac-Catalyst] Pulldown Button not showing image

Anyone know why the following code doesn't show an image in a Mac-catalyst toolbar? I've tried with both Label and Image.

I've attached an image of what this looks like.

This is with Xcode 13.4 running on Monterey, but Ive seen something similar with Xcode 14 and Ventura.

struct ContentView: View {
    var body: some View {
        NavigationView {
            Text("Hello, world!")
                .padding()
                .toolbar {
                    ToolbarItemGroup(placement: .primaryAction) {
                        Menu(content: {
                            Button("Test", action: {})
                        }, label: {
//                            Label("Menu", systemImage: "plus")
                            Image(systemName: "plus")
                        })
                    }
                }
        }
    }
}
