AttributeGraph: cycle detected through attribute In Sheet

Hi. I am not sure why i get the error message AttributeGraph: cycle detected through attribute

but this does happen i noticed if i have a Text component render html.

Here is the code

import SwiftUI

struct ContentView: View {
  @State private var isShowingAlertSheet = false
  @State private var alertTitle: String?
  @State private var alertDescription: String?
   
  var body: some View {
    VStack {
      Button(
        "click me", action: {
          alertTitle = "TITLE HERE"
          alertDescription = "<b>hey</b>"
          isShowingAlertSheet = true
        }
      )
    }
    .sheet(isPresented: $isShowingAlertSheet) {
      DetailView(alertTitle: $alertTitle, alertDescription: $alertDescription)
    }
  }
}

struct ContentView_Previews: PreviewProvider {
  static var previews: some View {
    ContentView()
  }
}

struct DetailView: View {
   
  @Binding var alertTitle: String?
  @Binding var alertDescription: String?
   
  var body: some View {
    VStack {
      Text(alertTitle ?? "")
        .font(.system(size: 20))
        .padding(.top, 10)
        .padding(.bottom, 0)
        .presentationDetents([.height(250)])
      Text(fixTextSize(alertDescription?.htmlMutableAttributedString))
        .frame(maxWidth: .infinity)
        .padding(.top, 10)
      Spacer()
    }
    .padding()
  }
   
  func fixTextSize(_ mutableAttributedString: NSMutableAttributedString?) -> AttributedString {
    if let mutableAttributedString {
      mutableAttributedString.addAttribute(NSAttributedString.Key.font, value: UIFont.systemFont(ofSize: 16), range: NSMakeRange(0, mutableAttributedString.length))
      return AttributedString(mutableAttributedString)
    }
    return AttributedString()
  }
}

extension String {
  var htmlMutableAttributedString: NSMutableAttributedString? {
    if let attributedString = try? NSMutableAttributedString(data: Data(self.utf8), options: [.documentType: NSAttributedString.DocumentType.html], documentAttributes: nil) {
      attributedString.addAttribute(NSAttributedString.Key.foregroundColor, value: UIColor(.black), range: NSMakeRange(0, attributedString.length))
      return attributedString
    }
    return nil
  }
}

Thoughts?
