Steps to replicate the issue (include links if applicable):

• Visit https://meta.wikimedia.org/wiki/Special:CentralAuth?target=Vermont (or for any other user)

What happens?:

• Sort by edit count: most local user groups which my account is a member of are not shown, except for Meta.
• Sort by groups: many projects where I do not have user groups, groups are shown. E.g., global-renamer on mnwwiktionary, autopatrolled on a bunch of projects.

What should have happened instead?:

• CentralAuth should show the user groups that the account has
