The issue is reproducible only in a specific setup with a specific document. It is related to the calculations of the line spacing when the table row should be split between two pages.
Workaround: Change the line spacing:
foreach (var paragraph in this.document.EnumerateChildrenOfType<Paragraph>())
{
paragraph.Properties.LineSpacingType.LocalValue = HeightType.Auto;
paragraph.Properties.LineSpacing.LocalValue = 1;
}
