Test case 576 is about the 'group' role, where authors must place legitimate descendants within the group (e.g., for list, the group must have listitems). The *general* expected result for test case 576 does make sense. It says: "Accessibility test tool flags an error indicating a failure to have the required child elements." On the other hand, the expected result by platform states that the object is hidden. For example, the ATK/AT-SPI expected result says: "Object attributes include hidden:true" Why the focus on hiding when this is a test of valid parent/descendants relationships?
Having heard no objections, I've cleared all of the the expected result by platform. Now, only the general expected result applies.
