Well, I got side-tracked by a bunch of tech debt and other bugs in related parts of the codebase, but eventually got to fixing this: fix: improve metadata of Edition pages by agilgur5 · Pull Request #3729 · suttacentral/suttacentral · GitHub
Also found and fixed another visible bug on this page while I was at it: fix: don't set the toolbar title to `''` for `EditionMatter` pages by agilgur5 · Pull Request #3726 · suttacentral/suttacentral · GitHub
EDIT:
This was reported again and I figure I could fix this myself now that I understand the code paths, so I made a draft PR for that: Add initial entries for `viewoption:ptsRefs` (EN, RU, ES) by agilgur5 · Pull Request #5298 · suttacentral/bilara-data · GitHub
Added some translations from languages I can read/write with some proficiency in as well, and some related missing ES translations too.
These should probably be done from within the Bilara app though, but I don’t have access to it currently, so made manual PRs for now. I’m also not sure how the workflow for new interface localization keys should work.
