Metadata issue when using ApiMemberAttribute and PropertyInfo.AddAttributes

ServiceStack Metadata
1

Starting in v6.4, DTO properties with an ApiMemberAttribute added at runtime via PropertyInfo.AddAttributes are not displaying the attribute’s Description property in the metadata page or code.

Using the blank .NET 6 template, adding

typeof(Hello)
  .GetProperty("Name")
  .AddAttributes(
      new ApiMemberAttribute
      {
          ParameterType = "path",
          Name = "MetaName",
          DataType = "foo",
          Description = "The name of the person to say hello to.",
          IsRequired = true,
      },
      new DataMemberAttribute());

results in the description being displayed in metadata in v6.3 and below:

However, starting with v6.4, the description is no longer displayed - although other attributes such as datatype, IsRequired, etc., as well as a dynamically added DataMemberAttributes, are.

Annotating the property itself in code still works; see HelloResponse.
