Buttons in the bottom bar of an inspector appear disabled

Buttons placed in the bottomBar and keyboard toolbar item positions in an inspector appear disabled/grayed out when at the large presentation detent.

The same is not true for sheets.

Is this intentional or a bug? If intentional, is there any backing design theory in the Human Interface Guidelines for it?

Xcode 16.4 / 18.5 simulator

// Inspector @ large detent
struct ContentView: View {
    var body: some View {
        Color.clear
            .inspector(isPresented: .constant(true)) {
                Color.clear
                    .presentationDetents([.large])
                    .toolbar {
                        ToolbarItem(placement: .bottomBar) {
                            Button("Save") {}
                                .border(.red)
                        }
                    }
            }
    }
}

// Sheet
struct ContentView: View {
    var body: some View {
        Color.clear
            .sheet(isPresented: .constant(true)) {
                Color.clear
                    .presentationDetents([.medium])
                    .toolbar {
                        ToolbarItem(placement: .bottomBar) {
                            Button("Save") {}
                                .border(.red)
                        }
                    }
            }
    }
}
