The error reported is on the wrong patch. Not sure why, but the problem
is here. With 'additionalProperties: false', this property is not
factored in and is considered unknown. That can be fixed using
'unevaluatedProperties', but instead, move this to the top level
'properties'.

The first example is enough.
