Strange behaviour with NavigationView and Buttons

I'm getting really strange results when pushing views onto a NavigationView stack and using buttons. This happens in the latest Xcode beta. Sample code:

struct TestView: View {
    var body: some View {
        NavigationView {
            VStack {
                NavigationLink("To view 2", destination: View2()) // Doesn't work
                NavigationLink("To view 3", destination: View3()) // Works
            }
            .navigationTitle("View 1")
            .navigationBarTitleDisplayMode(.large)
        }
    }
}

struct View2: View {
    var body: some View {
        VStack {
            NavigationLink("To view 3", destination: View3())
        }
        .navigationTitle("View 2")
        .navigationBarTitleDisplayMode(.large) // Setting to .inline makes it work
    }
}

struct View3: View {
    var body: some View {
        VStack {
            Button("Button 1") { print("Button 1") }
            Button("Button 2") { print("Button 2") }
            Button("Button 3") { print("Button 3") }
            Button("Button 4") { print("Button 4") }
            Button("Button 5") { print("Button 5") }
            Spacer() // Removing this makes it work
        }
        .navigationTitle("View 3")
        .navigationBarTitleDisplayMode(.inline)
    }
}

There are three views. View1 has links to View2 and View3. View2 has a link to View3. View3 has a number of buttons.

If I go View1 -> View3, everything works. If I go View1 -> View2 -> View3, the first 2-3 buttons don't work.

If I remove the Spacer() from View3, it works. If I change the navigationBarTitleDisplayMode of View2 to .inline, it works.

This looks like a bug to me. Are there any workarounds?
