drupal 8 how do i find out what's producing pager_default_initialize

Pager missing on pages greater than 1, but returns on a refresh https://www.drupal.org/project/search_api/issues/3000344


We’re working around this somehow in Find It (code base is public) but i know the main search pager is still adding a number when i think i should be able to show no number, even after partially fixing this (patch/fix in Search API Solr if i recall) so that it doesn’t have to start at 6 or something.
