Since it is a fictional character, she doesn't really have her own opinion. That is just the opinion of the author(s); which wikis are not obliged to adhere to. So the fact that she refers to herself with those pronouns in canon does not automatically make it bad behavior for someone to not use those pronouns.

In this particular case, however, the opinion of the author(s), the opinion of the other admins, and the opinion of the rest of the community are all aligned (assuming what you say is true). So yeah, in this case, I would say the admin in question is a problem.
