The GENDER support in the moderation messages in Flow is quite broken.
I fixed some of the client-side support in https://gerrit.wikimedia.org/r/#/c/98368/ , however there's another important thing to fix: The flow-moderation-confirmation-* messages are used client-side and they need not just the target user name, but the gender. That's because JavaScript can't determine the gender of a user other than the current one. The target user's gender must be passed as 'male' or 'female' from the server side somehow. Maybe another data attribute.
Looking at the current translations, there's at least one language in which gender support is needed ('mk').
