A bit naively I tried to use DokuWiki + Prosemirror on a PHP 8 only installation which ATM does not work; DokuWiki seems to run fine, but Prosemirror still uses the Doku_Form class, in particular the HTML_EDITFORM_OUTPUT event is no longer generated as seemingly the DokuWIki editor already uses the new form class.
