The child view onAppear is not fired consistently with .bottomSheet but it is consistent when using .sheet.

Describe the bug
The child view onAppear is not fired consistently with .bottomSheet but it is consistent when using .sheet.

Minimal reproduce-able code

struct TabbedViewWithBottomSheet: View {
    @State var bottomSheetPosition: BottomSheetPosition = .hidden
    @State var sheetContent: any View = EmptyView()
    @State var showSheet: Bool = false
    
    var body: some View {
        TabView {
            VStack {
                Button("show1") {
                    sheetContent = ChildView1(name: "Show1 sheet1")
                    bottomSheetPosition = .relativeTop(1)
                }
                Button("show2") {
                    sheetContent = ChildView1(name: "Show2 sheet2")
                    bottomSheetPosition = .relativeTop(1)
                }
                Button("show3") {
                    sheetContent = ChildView1(name: "Show3 sheet3")
                    showSheet.toggle()
                }
                Button("show4") {
                    sheetContent = ChildView1(name: "Show4 sheet4")
                    showSheet.toggle()
                }
            }
            .bottomSheet(
                bottomSheetPosition: self.$bottomSheetPosition,
                switchablePositions: [.relativeTop(1), .hidden]
            ) {
                AnyView(sheetContent)
            }
            .enableSwipeToDismiss()
            .showCloseButton()
            .sheetWidth(BottomSheetWidth.relative(1))
            .tabItem {
                Image(systemName: "magnifyingglass")
                Text("Search")
            }
            .tag(0)
            
            Text("Lists content")
                .tabItem {
                    Image(systemName: "list.dash")
                    Text("Lists")
                }
                .tag(1)
        }
        .sheet(isPresented: $showSheet) {
            AnyView(sheetContent)
        }

    }
}

struct ChildView1: View {
    var name: String
  
    var body: some View {
        VStack {
            Text("Hello, \(self.name)!")
        }
        .onAppear {
            print("ChildView1.onAppear \(self.name)")
        }
    }
}

Expected behavior
I expect the onAppear to fire in the ChildView every time the bottom view is not hidden. If I have logic that fires in the onAppear to populate the view from an API this doesn't fire and the previous view content is shown instead.
