I can confirm that this doesn’t replace the attached file with PDF
documents too (so it might be a bug).

Sorry, but I cannot follow. Embedded files (as opposed to [file]
attachment annotations) are not anchored in pages (afaIk).

Then, if old-invoice.pdf has a single embedded file, it will have only a
single embedded file in all (or each) of its pages.
