Double sheet can not be dismissed

There is a constructure using double sheet in my app, which open a sheet to edit a item(depth 1), and it can open another sheet to edit the field in the item (depth 2). In my case, I have encountered a bug that if I go down to the second sheet(depth 2), and then I dismiss the second sheet(depth 2), then I can't dismiss the first sheet(depth 1)

here is the sample code, I test it in Xcode 14.1 RC2 and ios16.1 on both simulator and physical devices.

import SwiftUI
import CoreData

struct ContentView: View {
    @State private var isSubPresented = false
    @Environment(\.dismiss) var dismiss
    var body: some View {
        Text("Main")
            .sheet(isPresented: $isSubPresented) {
                VStack {
                    SubView()
                    
                    Button("dismiss") {
//                        dismiss() // not work at all
                        isSubPresented = false
                    }
                    .padding()
                }
            }
            .onTapGesture {
                self.isSubPresented = true
            }
    }
}

struct SubView: View {
    
    @State private var isPresented: Bool = false
    @Environment(\.dismiss) var dismiss
    var body: some View {
        Button("into Sub edit") {
            self.isPresented = true
        }
            .sheet(isPresented: $isPresented) {
                Form {
                    
                    Button("dismiss") {
                        dismiss()
                    }
                }
            }
    }
}


struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView().environment(\.managedObjectContext, PersistenceController.preview.container.viewContext)
    }
}
