"My Settings" link using custom domain

We have a custom domain setup with custom branding and that is all working well. Our admins are using the default okta.com domain for the admin tooling (as expected), however when they click the My Settings link under their profile, it is using the custom domain instead of the default okta.com, so the branding is not what we would expect for the internal admins. Is there a way to get that My Settings link to use the default okta.com domain instead of the custom one?
