Multipart endpoint [FromForm] decorated argument is missing from signature

[fearef]

Describe the bug
I have a receiving API endpoint with following signature:

[HttpPost("[action]/{bucketName}/{directory}", Name = nameof(UploadFileAsync))]
[ProducesResponseType(StatusCodes.Status200OK)]
[ProducesResponseType(StatusCodes.Status400BadRequest)]
public async Task<IActionResult> UploadFileAsync(string bucketName,
	[FromRoute] string directory,
	[FromForm] UploadFileArgs uploadFileArgs,
	IFormFile file,
	CancellationToken cancellationToken)

using refitter CLI i get the following contract generated for the controller:

 /// <summary>
 /// Returns information about file
 /// </summary>
 [System.CodeDom.Compiler.GeneratedCode("Refitter", "0.7.5.0")]
 public interface IFileApi
 {
     [Headers("Accept: application/json")]
     [Get("/v1/File/GetFileInfo/{bucketName}/{objectName}")]
     Task<FileInfo> GetFileInfoAsync(string bucketName, string objectName, CancellationToken cancellationToken = default);

     [Headers("Accept: application/octet-stream")]
     [Get("/v1/File/DownloadFile/{bucketName}/{objectName}")]
     Task DownloadFileAsync(string bucketName, string objectName, [Query] string versionId, CancellationToken cancellationToken = default);

     [Multipart]
     [Headers("Accept: application/json")]
     [Post("/v1/File/UploadFile/{bucketName}/{directory}")]
     Task UploadFileAsync(string bucketName, string directory, StreamPart file, CancellationToken cancellationToken = default);

     [Headers("Accept: application/json")]
     [Post("/v1/File/CopyFile/{fromBucketName}/{filePath}/{toDirectory}")]
     Task CopyFileAsync(string fromBucketName, string filePath, string toDirectory, [Query] string toBucketName, CancellationToken cancellationToken = default);

     [Headers("Accept: application/json")]
     [Post("/v1/File/MoveFile/{fromBucketName}/{fromFilePath}/{toFilePath}")]
     Task MoveFileAsync(string fromBucketName, string fromFilePath, string toFilePath, [Query] string toBucketName, CancellationToken cancellationToken = default);

     [Delete("/v1/File/DeleteFile/{bucketName}/{filePath}")]
     Task DeleteFileAsync(string bucketName, string filePath, CancellationToken cancellationToken = default);
 }

The endpoint in question is missing the long[] OrganizationalUnitIds which is a single property of the [FromForm] UploadFileArgs uploadFileArgs argument in the receiving endpoint. In line 545 of openApi spec the request body is defined as follows:

"requestBody": {
                    "content": {
                        "multipart/form-data": {
                            "schema": {
                                "type": "object",
                                "properties": {
                                    "OrganizationalUnitIds": {
                                        "type": "array",
                                        "items": {
                                            "type": "integer",
                                            "format": "int64"
                                        }
                                    },
                                    "file": {
                                        "type": "string",
                                        "format": "binary"
                                    }
                                }
                            },
                            "encoding": {
                                "OrganizationalUnitIds": {
                                    "style": "form"
                                },
                                "file": {
                                    "style": "form"
                                }
                            }
                        }
                    }
                }
