Summary: Navigation bar title ignores `navigationBarTitleDisplayMode` when NavigationView shown via `.sheet` and contained in conditional content view. Steps to reproduce: 1. Create SwiftUI iOS app with following implementation ``` import SwiftUI @main struct SheetNavApp: App { var body: some Scene { WindowGroup { ContentView() } } } struct ContentView: View { @State var showSheet = false var body: some View { Button("Show sheet") { showSheet = true } .sheet(isPresented: $showSheet) { SheetView() } } } struct SheetView: View { enum ViewState { case initial, navigationView } @State private var state: ViewState = .initial @ViewBuilder var body: some View { switch state { case .initial: VStack { Button("Show navigation") { state = .navigationView } } case .navigationView: NavigationView { VStack { Text("In navigation") } .navigationTitle("A title") .navigationBarTitleDisplayMode(.inline) } } } } ``` 2. Run app on iOS 15 device 3. Tap on 'Show sheet' button 4. Tap on 'Show navigation' button Observed behavior: Navigation bar title displayed in `large` mode. Expected behavior: Navigation bar title displayed in `inline` mode Note: In iOS 14.5 title displayed correctly. Also `.navigationBarHidden(true)` modifier does not work in this case as well.
