azure-sdk-for-java: Azure Blob - "BlobItem.getMetadata()" returns null but "BlobClient.getProperties().getMetadata()" returns correct value

We are using BlobContainerClient.listBlobsByHierarchy(..) to get list of blobs while iterating we realised that BlobItem.getMetadata() returns null but BlobClient.getProperties().getMetadata() returns correct value

Prerequisite Create a blob which should have metadata

Code Snippet To Reproduce

 public void getBlobMetadata() throws Exception {
        String containerName = "**-test";
        String directoryName = "**-test";

        BlobServiceClient blobServiceClient = new BlobServiceClientBuilder().endpoint(BLOB_SAS).buildClient();
        BlobContainerClient blobContainerClient = blobServiceClient.getBlobContainerClient(containerName);

        ListBlobsOptions listBlobOption = new ListBlobsOptions();
        listBlobOption.setMaxResultsPerPage(10);
        listBlobOption.setPrefix(directoryName);

        PagedIterable<BlobItem> pagedIterable = blobContainerClient.listBlobsByHierarchy(null, listBlobOption, null);
        Iterable<PagedResponse<BlobItem>> iterableByPage = pagedIterable.iterableByPage(10);

        Iterator<PagedResponse<BlobItem>> pagedResponseiterator = iterableByPage.iterator();
        while (pagedResponseiterator.hasNext()) {
            PagedResponse<BlobItem> pagedResponse = pagedResponseiterator.next();
            Iterator<BlobItem> pagedBlobItems = pagedResponse.getElements().iterator();
            while (pagedBlobItems.hasNext()) {
                BlobItem blobItem = pagedBlobItems.next();
                LOGGER.info("BlobItem - BlobName '{}', Metadata '{}'", blobItem.getName(), blobItem.getMetadata());

                BlobClient blobClient = blobContainerClient.getBlobClient(blobItem.getName());
                LOGGER.info("BlobClient - BlobName '{}', Metadata '{}'", blobItem.getName(), blobClient.getProperties().getMetadata());
            }
        }
    }

Expected behavior BlobItem.getMetadata() should return available metadatas
