What are you trying to achieve or the steps to reproduce ?

A new feature in Joi 14 is the ability to use nested paths in or/and/with (among others) as described in #1615. However according to my tests with seem to validate in an unexpected or faulty manner.

const schema = Joi.object().keys({
    a: {
      b: Joi.string()
    },
    c: {
      d: Joi.string()
    }
})
.with("a.b", "c.d");

So if a: {b: "..."} exists we want c: {d: "..."} to also exist.

Which result you had ?

If we have the following input

const data = {
  a: {
    b: "foo"
  }
};

Then the input is considered valid.

What did you expect ?

The input should not be valid as c.d does not exist.
