Exporting XLSX to PDF removes image in table header

What is the problem

When exporting/printing an .xlsx which has an image inside the “header” of the table (which should be shown when printing or exporting to PDF) it is not there any more.

But when i open the same .xlsx with Microsoft Excel or convert it via https://smallpdf.com/excel-to-pdf the image inside the header is present.

Yes, I know this is quite a specific problem but its something I need for my work.
Currently my workaround is to use the given service from smallpdf.com but I would rather prefer to convert it on my own server.

Here is an example .xlsx file which has an image as header set.

Used versions:
NC 17.0.3
OnlyOffice App 4.1.4
OnlyOffice Docker Document Server Image
