@Lina_Farid_WMDE although we can work around this as we progress with the Parsoid roll-out, I'm adding to your teams backlog to triage, so we can ensure these workarounds are not needed anymore.

Let me know if you have any questions or concerns.

I looked at one of the wikis a bit more closely, and I suspect some of the issue stems from the fact that wikis might have diverged their backlink rendering since I originally had added custom css counters and those css counters have persisted through all the work WMDE has done. So, the fix would be to update the counter styles for all these wikis in the Cite repo. For starters, at least for those wikis, where the backlink rendering is now indo-arabic numerals (vs custom numerals), the fix might be to remove the custom counter styles added in the Cite repo. Seems to be the case for ext.cite.style.as.less and ext.cite.style.lo.less.

In other cases, maybe we need a counter-style provided where one doesn't exist right now. Examples: sewiki, gvwiki, bewwiki.

Alternatively, we override them in Mediawiki:Common.css of those wikis.
