is R2 able to add metadata for "put object" commands ?

import {
  PutObjectCommand,
  S3Client
} from '@aws-sdk/client-s3';
import { getSignedUrl } from '@aws-sdk/s3-request-presigner';

...

const s3 = new S3Client({ ... });
const cmd = new PutObjectCommand({
  Bucket: c.env.BUCKET_NAME_VAULT_STORAGE,
  Key: fileKey,
  Metadata: {
    test: 'hello',
  },
  ContentType: file.type,
  ContentLength: file.size,
});

const url = await getSignedUrl(s3, cmd, { expiresIn: SIGNATURE_EXPIRATION_IN_SECONDS });

....(front end uploads to url)

import {
  PutObjectCommand,
  S3Client
} from '@aws-sdk/client-s3';
import { getSignedUrl } from '@aws-sdk/s3-request-presigner';

...

const s3 = new S3Client({ ... });
const cmd = new PutObjectCommand({
  Bucket: c.env.BUCKET_NAME_VAULT_STORAGE,
  Key: fileKey,
  Metadata: {
    test: 'hello',
  },
  ContentType: file.type,
  ContentLength: file.size,
});

const url = await getSignedUrl(s3, cmd, { expiresIn: SIGNATURE_EXPIRATION_IN_SECONDS });

....(front end uploads to url)

as you can see in the screenshot, no metadata was added to the file. metadata seems to work fine for multipart uploads, but not for single "put object" commands. is it working ok?
