Is it an issue related to Adaptive Cards?

No.

What is the PWD impact?

User Experience:

When users with low vision resize the page to the viewport of 320*256 pixel, it will be difficult for them to understand the content if the contents or controls on the page appear overlapped or truncated as they are the source of visual information on the page.

Pre-requisite:

Achieve viewport 320 X 256 by adjusting the browser. (Open the developer's tool, resize, and zoom the browser to achieve viewport 320 X 256).
