Layout broken when using rowspan with repeatable footer

[laurafeier]

Reproducible with:

idx = 0
rows = 31.times.map { [{ content: (idx += 1).to_s }] }
rows.first.unshift({ content: "col 1", rowspan: rows.count })

pdf = Prawn::Document.new

pdf.bounding_box([pdf.bounds.left, pdf.cursor], width: pdf.bounds.width) do
  pdf.table(rows, cell_style: { borders: [:bottom], border_colors: 'CCCCCC' })
end

pdf.repeat(:all) do
  pdf.bounding_box([pdf.bounds.left, pdf.bounds.bottom], width: pdf.bounds.width, height: 30) do
    pdf.text("footer")
    pdf.stroke_bounds
  end
end

Ruby version: 3.0.2
Prawn version: 2.4.0
Prawn table version: 0.2.2

Result: bug.pdf

Issues:

1. first page rows from the second columns are missing
2. first column's bottom border should be rendered on the second page, inline with the last row, not on the first page overlapping with the footer
