These are accessibility issues of v3 of Web Chat, which has been deprecated and we no longer support unless there are security risks. For accessible Web Chat, please migrate to v4.

@corinagum Yes the photos were against v3, however this issue is still present in v4. Please re-open this bug for tracking and tag with Accessibility

This is related to Adaptive Cards.

The content author is creating the bubble content (with 3 buttons) using hero card, which is then rendered by the Adaptive Card library. As you see, the class are prefixed with ac-, it means Adaptive Cards.

Please contact the Adaptive Card team for this issue.
