 * A mini suite providing an alternative to tests failing due to issues found in RN 58+ on Android (see
 * https://github.com/facebook/react-native/issues/23870).
 * It basically runs similar 'action' use cases -- all of which involve visibility and scrolling, but in a
 * setup where they <i>can</i> pass, so as to assert that the core Detox functionality is valid nevertheless.
