Missing page numbers with oneside mode

With oneside mode page numbers are missing after the chapter page. This was also reproduceable with the default thesis.tex. The used pdfTeX was 3.14159265-2.6-1.40.21 (TeX Live 2020/Arch Linux) kpathsea version 6.3.2

The attached patch fixed it for me (I seem to have no permissions to open a Merge Request…)
