Actuator does not display immutable configuration properties when using @Validated

When I added @Validated annotation to an immutable configuration properties class (using @ConstructorBinding), actuator configprops does not display its fields.

For example:

@Validated
@ConfigurationProperties(prefix = "prop.validated")
@ConstructorBinding
data class ValidatedProp(
    val field: String
)

actuator does not display its fields:

"prop.validated-com.example.demo2.ValidatedProp": {
  "prefix": "prop.validated",
  "properties": {}
}

This configuration properties class is correctly initialized and not impacted in my application.

When I remove either @Validated or @ConstructorBinding, actuator seems to display its properties correctly.

Here is my example project:
