[White Label-Card Bingsports]: Narrator does not navigate Card controls when using arrow keys.

Is it an issue related to Adaptive Cards?

No.

What is the PWD impact?

Screen reader users cannot explore the contents of a card using arrow navigation, forcing them to rely only on Tab. This results in slower, more cumbersome navigation and makes it difficult to understand the logical structure of the content.

What browsers and screen readers do this issue affect?

Windows: Edge with Windows Narrator

Start with the reproduction at the webchat-loader URL, using the specified 4.18.1-main version, Edge, and Windows Narrator. Inspect the card controls and their accessibility tree while testing arrow-key navigation; done means Narrator can move through the card controls in the expected logical sequence.
