{Linked:Bug49658986;Linked:Bug49357192;Linked:Bug49357930;Linked:Bug55956296}Feature request: Expose API to update a card with new data (template remains the same)

Target Platforms

AdaptiveCards-WinUI (=shared code with Universal)

SDK Version

1.0.2

Application Name

Dev Home, Windows Widget Dashboard

Problem Description

When the Adaptive Card of a Widget updates (either by an action pressed or not) and the focus is held inside the card, it is lost on the re-rendering. This happens because all the content of the card is redrawn when an update occurs.

The correct behavior should be the focus being kept to the equivalent control if the template didn't change from update to another. Or if the template changes, the focus should change to the AC itself. And the narrator should not narrate the control again when this change happen.

Start by tracing the AdaptiveCards-WinUI shared rendering and update path used by the provided card JSON, focusing on how focus and narrator state behave when card data changes. Define the API and update behavior for unchanged versus changed templates, then verify that equivalent controls retain focus and that Narrator does not repeat unchanged content.
