Actual Result:

In backward navigation it is announcing label information twice, it is announcing as 'Select host app select host app Bot Framework Webchat Bot framework web chat combo box collapsed has a pop up'.

Start at the Adaptive Cards designer and reproduce the behavior with Narrator or NVDA on the Host app and Target Version combo boxes, testing forward and backward tab navigation. Done means each combo box's label and selected option are announced only once in both directions.
