The PDF export has an extra blank page when selecting only the cover page option

Follow these steps to reproduce:

• Open any wiki page
• Export to PDF making sure to uncheck all options from the PDF Export Options modal, except for cover page{}{}

Expected results: the cover print page is followed by the content pages.

Actual result: there's a blank / empty page between the cover page and the content pages

I could reproduce this only on Firefox (110+).
