                    "value": "value3"
                }

    ]
}

Start by reproducing the issue in Web Chat with the Adaptive Card JSON in Firefox: select a ChoiceSet value, submit the card, then disable it after recent bot messages have been sent. Trace the affected Adaptive Card attachment behavior and verify that the selected input remains visible after disabling the card.
