The definition of aria-owns (https://www.w3.org/TR/2017/REC-wai-aria-1.1-20171214/#aria-owns) includes this statement: > If an element has both aria-owns and DOM children then the order of the child elements with respect to the parent/child relationship is the DOM children first, then the elements referenced in aria-owns. However, we have two methods that don't conform to this, instead choosing aria-owns _or_ DOM children, but not both. We should review and potentially change this behavior. The methods are: AccessibilityObject::ariaTreeRows AccessibilityTableRow::addChildren
