Adaptive Card inputs in the live region copy of new messages have no name and no value.

Changelog Entry

Fixed

• Fixed screen readers announcing new Adaptive Card inputs without their labels and values, in PR #5913, by @OEvgeny

Description

The live region copy of an Adaptive Card labeled text, number, date, and time inputs with their title, which they do not have, so they were announced without a name, and it dropped pre-filled values. The copy now names them as the transcript does (aria-label from label, otherwise their placeholder, so labels are read once) and pre-fills their values.

Design

• Kept the native controls (out of the tab order, as live region suggested actions are), so roles are still announced; inert would remove the whole copy from the accessibility tree.

Specific Changes

• AdaptiveCardAttachment.js (screen reader renderer): text, number, date, and time inputs get aria-label from label instead of a <label> with title text

• Added accessibility/liveRegion/attachment/adaptiveCard.inputLabel.html: inputs are named, labels are not repeated as text, inputs are out of the tab order; snapshot 1 shows the copy

• AdaptiveCardAttachment.js: inputs get defaultValue, toggles are checked from defaultValue (was always unchecked); adaptiveCard.inputValue.html snapshot 1 shows the values as in the card

• I have added tests and executed them locally

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

• I have updated documentation
