Update this task with a list of fully tested extensions, as they are tested. Note which issues they have and whether they should be removed, are an upgrade blocker, or any other relevant details.
**Only extensions or skins that seem to fully work without issue, or when the issue is acceptable to move forward with MediaWiki 1.40 deployment, should be checked off this list. Please also note blockers on the Production Blockers list of the parent task.**
Note: If upstream bugs are not resolved within a reasonable time, the upgrade is prioritized over individual extensions
