iTextSharp SetCharacterSpacing broken when using Right Align

I have a table with two cells. The first cell is left aligned and the second cell is right aligned. I also want to change the character spacing of the text. I have found that changing the character spacing breaks the alignment so the right align text ends up outside the boundaries if the table.

I have created some test code below and the link to the output PDF is in this link

Are there any alternatives or workarounds to getting the character spacing working well with the right alignment?

public void CharacterSpacingTest()
{
    float margin = 50;

    using (var stream = new MemoryStream())
    {
        Document document = new Document();
        document.SetPageSize(new Rectangle(PageSize.A4.Width, PageSize.A4.Height));
        document.SetMargins(margin, margin, 30f, 100f);

        PdfWriter writer = PdfWriter.GetInstance(document, stream);
        writer.CloseStream = false;

        document.Open();

        PdfPTable table = new PdfPTable(new float[] { 100 });
        table.TotalWidth = PageSize.A4.Width - margin - margin;
        table.WidthPercentage = 100f;
        table.LockedWidth = true;

        // Create a row that is right aligned
        PdfPCell cell1 = new PdfPCell();
        cell1.AddElement(new Paragraph("Hello World") { Alignment = Element.ALIGN_RIGHT });
        cell1.BorderWidth = 1;
        table.AddCell(cell1);

        // Change the character spacing
        PdfContentByte cb = writer.DirectContent;
        cb.SetCharacterSpacing(1f);

        // Create a row that is left aligned
        PdfPCell cell2 = new PdfPCell();
        cell2.AddElement(new Paragraph("Hello World"));
        cell2.BorderWidth = 1;
        table.AddCell(cell2);

        document.Add(table);

        document.Close();

        Blobs.SaveToFile(Blobs.LoadFromStream(stream), @"c:\Dev\test.pdf");
    }
}

I have managed to fix it by using chunks to set the character spacing. See amended code.

    public void CharacterSpacingTest()
    {
        float margin = 50;

        using (var stream = new MemoryStream())
        {
            Document document = new Document();
            document.SetPageSize(new Rectangle(PageSize.A4.Width, PageSize.A4.Height));
            document.SetMargins(margin, margin, 30f, 100f);

            PdfWriter writer = PdfWriter.GetInstance(document, stream);
            writer.CloseStream = false;

            document.Open();

            PdfPTable table = new PdfPTable(new float[] { 100 });
            table.TotalWidth = PageSize.A4.Width - margin - margin;
            table.WidthPercentage = 100f;
            table.LockedWidth = true;

            // Create a row that is right aligned
            PdfPCell cell1 = new PdfPCell();
            cell1.AddElement(new Paragraph(GetChunk("Hello World")) { Alignment = Element.ALIGN_RIGHT });
            cell1.BorderWidth = 1;
            table.AddCell(cell1);

            // Create a row that is left aligned
            PdfPCell cell2 = new PdfPCell();
            cell2.AddElement(new Paragraph(GetChunk("Hello World")));
            cell2.BorderWidth = 1;
            table.AddCell(cell2);

            document.Add(table);

            document.Close();

            Blobs.SaveToFile(Blobs.LoadFromStream(stream), @"c:\Dev\test.pdf");
        }
    }

    private Chunk GetChunk(string text)
    {
        Chunk chunk = new Chunk(text);
        chunk.SetCharacterSpacing(1);
        return chunk;
    }
