iOS 26 navigationTransition .zoom issue

When I dismiss a view presented with .navigationTransition(.zoom), the source view gets a weird background (black or white depending on the appearance) for a couple of seconds, and then it disappears. Here’s a simple code example.

import SwiftUI

struct NavigationTransition: View {
    @Namespace private var namespace
    
    @State private var isSecondViewPresented = false
    
    var body: some View {
        NavigationStack {
            ZStack {
                DetailView(namespace: namespace)
                    .onTapGesture {
                        isSecondViewPresented = true
                    }
            }
            .fullScreenCover(isPresented: $isSecondViewPresented) {
                SecondView()
                    .navigationTransition(.zoom(sourceID: "world", in: namespace))
            }
        }
    }
}

struct DetailView: View {
    var namespace: Namespace.ID
    
    var body: some View {
        ZStack {
            Color.blue
            
            Text("Hello World!")
                .foregroundStyle(.white)
                .matchedTransitionSource(id: "world", in: namespace)
        }
        .ignoresSafeArea()
    }
}

struct SecondView: View {
    
    var body: some View {
        ZStack {
            Color.green
            
            
            Image(systemName: "globe")
                .foregroundStyle(Color.red)
        }
        .ignoresSafeArea()
    }
}

#Preview {
    NavigationTransition()
}
