AX: supportsARIAExpanded should always return true for a few roles: treeitem, combobox, disclosure. Currently it's:

bool AccessibilityObject::supportsARIAExpanded() const
{
    // Undefined values should not result in this attribute being exposed to ATs unless.
    const AtomicString& expanded = getAttribute(aria_expandedAttr);
    return equalIgnoringCase(expanded, "true") || equalIgnoringCase(expanded, "false");
}

To whoever fixes this, run the inspector-protocol layout tests in addition to the accessibility tests.
