Anyone Worked With AsyncView By Ralf Ebert, Doesnt Work In TabView

struct Test {
var body: some View {
    AsyncView(
      operation: { try await getData("https://localhost") },
      content: { json
        Text("data retrieved")
      }
    )
  }

func getData(_ url: String) async throws -> String {
    return try await getRequest(url)
  }
}

static func getRequest(_ sourceData: String?, _ useWindowsChar1252: Bool = false) async throws -> String {
    guard let sourceData else {
      return ""
    }
     
    var request = URLRequest(url: URL(string: sourceData.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed)!)!)
    request.httpMethod = "get"
     
    let (data, _) = try await URLSession(configuration: .ephemeral).data(for: request)
    return useWindowsChar1252 ?
      String(data: data, encoding: .windowsCP1252)! :
      String(decoding: data, as: UTF8.self)
  }

You can just have one tab item in the TabView and the http request keeps on looping. any idea?

struct MyTabView: View {
   
  var body: some View {
TabView {
    Test()
        .tabItem {
          Label("test", systemImage: "leaf")
        }
}
}
}

Trying to understand the cause. Because If I put the AsyncView, say inside a ZStack, it works ok.

Thoughts?
