This bug is also present in OpenPDF versions 1.3.30, 1.3.0 and 1.2.1. So this is not a recent regression, and has been this way for a long time.

Is it possible to examine the generated .PDF file to see if the missing "rowspan7" line text is missing from the generated PDF file, or if the text line is just not visible.

So it's a question if the missing "rowspan7" line is generated at all by OpenPDF, or if it is generated in a way so that it is not visible when the row cell is part of a page wrap, or if the cell height is incorrect when crossing page wrap so that the extra text line is hidden by overflow.
