Hm, it looks like that was wrong from the beginning when Lars added that
in commit c1c9af312ed3 in 2019.  page-delimiter never had a different
default value and pdftotext always used just ^L (FORM FEED)...

Looking at what other modes do, I've set page-delimiter buffer-locally
to the form feed character in the new text contents buffer now, i.e.,
it's only fixed on master which I think is ok given that nobody except
you found the issue in the last 5 years.
