Inconsistent Handling of Missing Required Owned Elements

[WilcoFiers]

Accessibility support

Assistive technologies are not consistent in how they handle situations where a [required owned element][] has a missing or incorrect role. This can lead to situations where inaccurate owned elements behave as expected in one assistive technology, but not in another.

ACT Rules

• ARIA required owned elements - bc4a75
