In WebAccessibilityObjectWrapperMac.mm, we expose the document links attribute (AXLinkUIElements) on web areas. However, in AXIsolatedObject::initializeAttributeData we currently only store AXPropertyName::DocumentLinks for the root element, which is not a web area. This causes accessibility/visible-elements.html to fail. https://github.com/WebKit/WebKit/blob/109c8234854a0fa28955d81994bb98daa1fa14fe/Source/WebCore/accessibility/mac/WebAccessibilityObjectWrapperMac.mm#L2235#L2237
