swiftui - Right-to-left language not showing in Xcode preview from locale

Question

In my Xcode preview in a SwiftUI view, I'm testing different locales like this:

ForEach(["ar-SA", "tr-TR"], id: .self) { localIdentifier in
    ContentView()
        .environment(.locale, Locale(identifier: localIdentifier))
        .previewDisplayName("Locale: (localIdentifier)")
}

However, for Arabic in my example, it's showing left-to-right when it should be the opposite. It seems I have to manually do something like this:

ForEach(["ar-SA", "tr-TR"], id: .self) { localIdentifier in
    content
        .environment(.locale, Locale(identifier: localIdentifier))
        .modifier(if: localIdentifier.hasPrefix("ar-")) {
            $0.environment(.layoutDirection, .rightToLeft)
        }
        .previewDisplayName("Locale: (localIdentifier)")
}

I thought the right-to-left should automatically be picked up from the locale. Is there something I'm missing so I don't have to explicitly set the layoutDirection and automatically read from the supplied locale?
