SwiftUI rendering path optimisation for `let` values

Hello colleagues,

I have question regarding passing data that doesn't need to change. In video suggested to use let, and it totally make sense! But I also found following issue: https://forums.raywenderlich.com/t/question-regarding-chapter-8-4/136398/2

I am wondering how to avoid rendering path optimisation to make sure it's not cached somewhere in between? Or was this something already fixed in prior SwiftUI versions?

My example:

struct ModelDetailsView {
    @ObservedObject var viewModel: ViewModel

    @ViewBuilder
    var body: some View {
        ModelItemsSection(viewModel.$model.subitems)
         .onAppear(perform: {
            self.viewModel.load()
        })
    }
}


struct ModelItemsSection: View {
    let items: [ModelSubitem] // simple struct

    var body: some View {
                PreviewItemsView(items: items, 
                                                 allItemsTitle: "All Items") { item in
                     Text(item.titleDetail + item.subtitle)
                } allItemsView: { items in
                    //3rd level screen where `let` data is passed that's destination to NavigationLink
                    AllModelItemsView(items: items)
                }
    }
}

Thanks, Dzmitry.
