This line changes padding top to align cell content to baseline:
`cell.padding_top += m_rows[cell.row_index].baseline - cell.baseline`
Which means available for distribution height `height_diff` could have
changed so it needs to be refreshed before assigning the rest of it to
padding bottom:
`cell_state.padding_bottom += height_diff;`
