API "user add email" sends confirmation despite skip_confirmation=True

Using self-hosted GitLab v17.1.0-ee.

As an admin, I am trying to add emails to existing user accounts via the API, without sending additional confirmation mails to the users.

The docs (Users API | GitLab) list the flag “skip_confirmation” as an option to skip the confirmation. This works in the sense, that the added email is automatically flagged as verified in GitLab, but the user still gets a mail from GitLab, asking them to confirm their newly added email address. If users now click on this link, they receive an error message, stating that the email was already verified (which it was due to setting the flag), which creates confusion on the user end.

Is there any way to disable the confirmation emails being sent from GitLab when adding secondary emails to users?
