SwiftUI Dismiss keyboard in modal issue

Hello,

I have an issue with the automatic keyboard dismissing in a modal : If I present a modal with textfields, and I try to dismiss the modal to close the keyboard, the keyboard disappear (that's good) but it leave some space...

Here is the example :

And here is my code to reproduce the issue (iOS 16, real device) :

struct ContentView: View {
    @State private var isViewPresented: Bool = false

    var body: some View {
        Button {
            isViewPresented = true
        } label: {
            Text("Show View")
        }
        .sheet(isPresented: $isViewPresented) {
            FormView()
        }
    }
}

struct FormView: View {
    var body: some View {
        NavigationView {
            ScrollView {
                VStack(spacing: 32) {
                    TextField("Text 1", text: .constant(""))
                        .frame(height: 42)
                        .background(Color.red)
                    TextField("Text 2", text: .constant(""))
                        .frame(height: 42)
                        .background(Color.red)
                    TextField("Text 3", text: .constant(""))
                        .frame(height: 42)
                        .background(Color.red)
                    TextField("Text 4", text: .constant(""))
                        .frame(height: 42)
                        .background(Color.red)
                }
            }
            .background(Color.yellow)
            .navigationTitle("Form view")
        }
    }
}

As you can see, when I start to dismiss the modal, the keyboard disappear and then there is a black space who appears...

Any suggestions ?

Thanks,

Alexandre
