iOS 26+ UITabBar unselected item colors not updating with UITabBarAppearance

I'm using UITabBarAppearance to customize my TabBar in a SwiftUI app. The customization works perfectly on iOS 18 and earlier, but after updating to iOS 26, the unselected tab items no longer respect my color settings - they just appear black (they are on a white background).Here's my simplified setup:

struct ContentView: View {
    var body: some View {
        TabView {
            Text("Home")
                .tabItem {
                    Image(systemName: "house")
                    Text("Home")
                }
                .tag(0)
            
            Text("Settings")
                .tabItem {
                    Image(systemName: "gear")
                    Text("Settings")
                }
                .tag(1)
        }
        .onAppear {
            setupTabBarAppearance()
        }
    }
    
    private func setupTabBarAppearance() {
        let appearance = UITabBarAppearance()
        appearance.configureWithOpaqueBackground()
        
        let itemAppearance = UITabBarItemAppearance()
        
        // These settings work for selected items
        itemAppearance.selected.iconColor = .systemBlue
        itemAppearance.selected.titleTextAttributes = [
            .font: UIFont.systemFont(ofSize: 10),
            .foregroundColor: UIColor.systemBlue
        ]
        
        // These settings STOPPED working on iOS 26 for unselected items
        itemAppearance.normal.iconColor = .gray
        itemAppearance.normal.titleTextAttributes = [
            .font: UIFont.systemFont(ofSize: 10),
            .foregroundColor: UIColor.gray
        ]
        
        appearance.stackedLayoutAppearance = itemAppearance
        appearance.inlineLayoutAppearance = itemAppearance
        appearance.compactInlineLayoutAppearance = itemAppearance
        
        UITabBar.appearance().standardAppearance = appearance
        UITabBar.appearance().scrollEdgeAppearance = appearance
    }
}
