Excel print scaling settings not respected

The Excel 2016 print scaling settings are not respected in LibreOffice 5.2.3.3.

Example:

  • In Excel, a spreadsheet has its “Custom Scaling” for printing set to 45% of normal size.
  • When opening the workbook in LibreOffice, this value is not respected
  • I can then set the scaling down to 45% in LibreOffice and save the workbook as .ods, which will - upon reopening - retain this value
  • I can then set the scaling down to 45% in LibreOffice and save the workbook as .xlsx, which will - upon reopening - NOT retain this value
