Issues with Non-Supported/Prohibited ARIA Attributes in Bot Framework

Is it an issue related to Adaptive Cards?

No.

What is the PWD impact?

During an accessibility audit, the following issues with ARIA attributes were found:

• aria-labelledby on Non-Semantic Elements:

Issue: aria-labelledby is used on non-semantic elements like

, which may cause assistive technologies to read the content instead of the attribute’s value.
Recommendation: Use semantic elements (e.g., , ) or add appropriate roles to improve accessibility.

• aria-invalid Set to False:

Issue: Setting aria-invalid to false is equivalent to not using the attribute, which provides no useful information to assistive technologies.
Recommendation: Set aria-invalid to true only when validation fails.

• aria-disabled Set to False:

Issue: Setting aria-disabled to false before validation or form submission doesn’t convey the element’s disabled state to assistive technologies.
Recommendation: Set aria-disabled to true when the element is disabled.
