SwiftUI and ScrollView: Views Disappear After Device Rotation

The view is composed with SwiftUI, and the List contains several rows where each row holds a ScrollView with the items. It is similar to Apple's SwiftUI Landmark tutorial (https://developer.apple.com/tutorials/swiftui/composing-complex-interfaces). When I rotate the device (tested on real iPhone XS), the content of the ScrollView disappears. The issue is not present when I replace the ScrollView with another element, such as Text. Thus, the issue must somehow be related to the use of ScrollView. Please see below the screenshots and the SwiftUI code.

Behavior

Code

struct ContentView: View {
    @FetchRequest(
        entity: InsigniaContainer.entity(),
        sortDescriptors: [
            NSSortDescriptor(keyPath: \InsigniaContainer.sort, ascending: true),
        ],
        predicate: NSPredicate(format: "parentContainer == NULL")
    ) var insigniaContainers: FetchedResults<InsigniaContainer>

    var body: some View {
        NavigationView {
            List {
                ForEach(self.insigniaContainers, id: \.objectID) { (insigniaContainer: InsigniaContainer) in
                    ServiceBranchRow(serviceBranch: insigniaContainer)
                }
                .listRowInsets(EdgeInsets())
            }
            .navigationBarTitle("Armed Forces")
        }
        .navigationViewStyle(StackNavigationViewStyle())
    }
}



struct ServiceBranchRow: View {
    var serviceBranch: InsigniaContainer

    var body: some View {
        VStack(alignment: .leading, spacing: 0) {
            Text(self.serviceBranch.wrappedName)
                .font(.headline)
                .fontWeight(.heavy)
                .padding(.leading, 15)
                .padding(.top, 10)
            Spacer()
            ScrollView(.horizontal, showsIndicators: false) {
                HStack(spacing: 15) {
                    ForEach(self.serviceBranch.sortedChildContainers, id: \.objectID) { item in
                        NavigationLink(destination: InsigniaList(insigniaContainer: item)) {
                            ServiceBranchItem(item: item)
                        }
                    }
                }
                .padding(10)
                .padding(.leading, 5)
                .padding(.trailing, 5)
                .padding(.bottom, 5)
            }
        }
    }
}
