encapsulated date component not genereted

Since the version 5.4.0, the code generation of the following component via the spring generator generates the following model

schemas: 
    Person:
      type: object
      properties:
        id:
          $ref: '#/components/schemas/ID'
        birthDate:
           $ref: '#/components/schemas/Date'
    ID:
      type: integer
      format: int64
      description: Unique identifier
      example: 1255266
    Date:
      type: string
      format: date
      description: A particular point in the progression of time in a calendar year expressed in the YYYY-MM-DD format. This representation is aligned with ISO 8601.
      example: "2020-02-15"

public class PersonApi   {

  @JsonProperty("id")
  private Long id;

  @JsonProperty("birthDate")
  private DateApi birthDate;

  public PersonApi id(Long id) {
    this.id = id;
    return this;
  }

And the DateApi object is not being genertated or present in the import

Here is the configuration

<generatorName>spring</generatorName>
<modelNameSuffix>Api</modelNameSuffix>

In version 5.3.1, the following is being generated

public class PersonApi   {
  @JsonProperty("id")
  private Integer id;

  @JsonProperty("birthDate")
  private java.util.Date birthDate;

It's worth noting that a quick workaround would be to inline the date directly.

Start by reproducing the issue with the Spring generator, the shown schema, and the modelNameSuffixApi configuration. Compare generation from versions 5.4.0 and 5.3.1. Done means the referenced date component is generated and imported appropriately, or the behavior is otherwise corrected with coverage for the encapsulated date schema.
