-* For the first instace, the annotation result of `properties` is [ "foo" ], and the annotation result of `patternProperties` is [ "bar" ]. However, the 'fooBar' property remains unevaluated, so the `unevaluatedProperties` subschema applies to it. This subschema fails (as any instance against a false schema is always invalid), leading to the failure of the entire schema.
