The live region reads Adaptive Card text with its Markdown and {{DATE()}} syntax, such as "**sunny**", instead of the text the card shows.

Changelog Entry

Fixed

• Fixed screen readers reading Adaptive Card text with its Markdown and {{DATE()}} syntax, in PR #5929, by @OEvgeny

Description

Since #5922 the live region reads the raw card text, so screen readers say asterisks, link URLs, and {{DATE(...)}}. Text blocks, rich text blocks, and facts are now rendered with the visible card's Markdown engine and read with htmlTextAlternatives(), as message text is.

Design

• Renders with Adaptive Cards ({{DATE()}}/{{TIME()}}, then Markdown) instead of stripping Markdown, so the live region reads what the card shows.

Specific Changes

• activityAltText.ts: htmlTextAlternatives() takes any node, exported through internal.js

• setMarkdownEngine.ts: moved out of renderAdaptiveCard.ts for reuse

• AdaptiveCardAttachment.js: reads the rendered text (raw text if rendering throws)

• adaptiveCard.markdown.html: snapshot 1, reads the card text without Markdown syntax

• adaptiveCard.dateTime.html: snapshot 1, reads the date and time as the card shows them

• adaptiveCard.imageAndBlocks.html: snapshot 1, reads image alt text and separates HTML blocks

• CHANGELOG.md: entry

• I have added tests and executed them locally

• I have added .changelog/<PR#>-<slug>.md

• I have updated documentation
