Example file from Excel with 28.35 pt (1cm) row heights saved, but displayed as smaller values

Attached file was made in Excel by setting 2 cm margins and 1 cm row heights.
This results on screen 26 visible rows on one A4 page: 29.7 cm – 4 cm margins = 25.7 cm. But: 26 1 cm rows mathematically should not fit in 25.7 cm space, yet they do.
In Calc however only 25 rows are visible in page layout view / print.

This is related to bug 120288
What really happens there is that Excel displays row heights in 0.75 point increments, so 1 cm becomes 9.79 mm.
On the other hand, it writes to XLSX files the user input value, this is what Calc displays.
This is a bit of cheating (also happens with Calc-saved XLSX files in Excel), this results in more rows being displayed than what could fit in the available vertical space.

Steps to reproduce:
1.	Open attached file in Excel and Calc, go to layout view.

Actual results:
Excel shows 26 rows, Calc shows 25 on one page.

Expected results:
Probably Calc should do this kind of cheating somehow for Excel-made files.
