SwiftUI view content layout unexpectedly pop / jumps on appear?

Providing a section with a header text fixes the issue, even if the text is blank. Although this will leave a gap between the navigation title and first row.

Works with both Forms & Lists styled as grouped.

struct TestView: View {

    var body: some View {
        Form {
            Section(header: Text("")) {
                Text("Test View")
            }
        }
        .nvigationBarTitle("Test View")
    }
}
