CELLSJAVA-42763 - Export PDF is cutting text horizontally
Please check attached file “TEST_By_Microft Excel 2016.pdf” saved by Microsoft Excel 2016, you will find the text is also cut between page 2 and page 3. It is because that page breaks are in merged cell area (e.g. merged cell A9), text line in the merged cell will have the choice being at the page break, so the text line will be cut between pages.

A workaround is splitting the large merged cell area to several areas to let pages breaks outside the merged cell instead of in the merged cell.
