Rowspan not working properly in OpenPDF 3.0

[cyChop]

Describe the bug

Rowspan isn't applied properly, though I observe different behaviors and cannot explain them.

To Reproduce

import java.io.File;
import java.io.FileOutputStream;
import org.openpdf.text.Chunk;
import org.openpdf.text.Document;
import org.openpdf.text.PageSize;
import org.openpdf.text.pdf.PdfPCell;
import org.openpdf.text.pdf.PdfPTable;
import org.openpdf.text.pdf.PdfStream;
import org.openpdf.text.pdf.PdfWriter;

//TIP To <b>Run</b> code, press <shortcut actionId="Run"/> or
// click the <icon src="AllIcons.Actions.Execute"/> icon in the gutter.
public class Main {
    static void main() throws Exception {
        Document document = new Document(PageSize.A4, 10, 10, 10, 10);
        File file = new File("test.pdf");
        FileOutputStream fos = new FileOutputStream(file);
        PdfWriter writer = PdfWriter.getInstance(document, fos);

        writer.open();
        writer.setFullCompression();
        writer.setCompressionLevel(PdfStream.BEST_COMPRESSION);
        document.open();

        float width = document.getPageSize().getWidth() - 20;

        float[] columns = {50f, 50f};
        PdfPTable table = new PdfPTable(columns);
        table.setTotalWidth(width);
        table.setLockedWidth(true);
        table.setHeaderRows(1);

        PdfPCell cell = new PdfPCell();
        cell.setRowspan(2);
        cell.addElement(new Chunk("rowspanrowspanrowspanrowspanrowspanrowspanrowspanrowspanrowspanrowspanrowspanrowspanrowspanrowspanrowspan"));
        table.addCell(cell);

        table.addCell("row1");
        table.addCell("row2");
        document.add(table);

        document.close();
        writer.close();
        fos.close();
    }
}

Expected behavior

The left column should be one single cell spanning two rows.

Screenshots

From the sample code:

If the Chunk's content is reduced to a single "rowspan":

Interestingly enough, from my (unstable) non-sample code (migration from iText 9 in progress). The empty sections should be filled by the rowspan=5 cells. This also goes to prove there's no issue with colspan.

Asking me this on a public form isn't really good form, and I don't understand the purpose of proving my identity. I am not a chatbot and my account's history should prove it, if that's the concern. Anyway, click my name, it'll show up on my profile.
