Steps to reproduce

1. Download the attached project
2. Build test_accessibility_root.pro in Debug mode
3. Copy external_accessibility_scan.app into the same folder as test_accessibility.app
4. Run test_accessibility.app
5. Click "Start External Test" (if permissions are requested, provide them and restart the test)
6. Click "Start Internal Test"

The test passes, always
