Using @example with a Field Reference from Another Model

[akishichinibu]

https://typespec.io/playground/?c=QGV4YW1wbGUoI3sKICBmaWVsZDogImZvbyIsCn0pCm1vZGVsIFggyx1zdHJpbmc7Cn0KCs49cmVm0jtZxTvFG1guxULEOg%3D%3D&e=%40typespec%2Fopenapi3&options=%7B%7D

I have the following code:

@example(#{
  field: "foo",
})
model X {
  field: string;
}

@example(#{
  ref: "foo",
})
model Y {
  ref: X.field;
}

The second ref: "foo" in example will cause an error.

Type '"foo"' is not assignable to type 'X.field'

Is it a syntax issue or a TypeSpec bug with @example?

Use case: I want to reuse a part of model in another operation and attach a new example in the spec.
