SwiftUI - Navigation bar button not clickable after sheet has been presented

Question

I have just started using SwiftUI a couple of weeks ago and i\'m learning. Today I ran into a into an issue.

When I present a sheet with a navigationBarItems-button

I think this happens because the presentationMode is not inherited from the presenter view, so the presenter didn't know that the modal is already closed. You can fix this by adding presentationMode to presenter, in this case to ContentView.

struct ContentView: View {

    @Environment(\.presentationMode) var presentation
    @State var showSheet = false

    var body: some View {
        NavigationView {
            VStack {
                Text("Test")
            }.sheet(isPresented: self.$showSheet) {
                ModalView()
            }.navigationBarItems(trailing:
                Button(action: {
                    self.showSheet = true
                }) {
                    Text("SecondView")
                }
            )
        }
    }
}

Tested on Xcode 11.5.

Here is the full working example.
