Reproduziere das Problem im Model Builder Value Prediction-Flow mit Narrator und NVDA und konzentriere dich auf das Dropdown-Menü "Column to predict". Verfolge den Barrierefreiheitsstatus des Steuerelements und überprüfe, dass die abgeschlossene Änderung nicht mehr dazu führt, dass einer der beiden Screenreader es als schreibgeschützt ankündigt.
