Expected / Desired Behavior / Question

I search for a user in the peoplePicker and select the user. I expect that the same user is shown

Observed Behavior

I search for a user who has a nromal acocunt and an admin account. The normal account ist test@test.com, the admin account ist adm_test@test.com.
The Adm account has OtherMails set to test@test.com. The drop down shows both users(which is correct), but when i select the normal account, suddenlt the people picker shows the Admin.
My explanation is that there is a call to https://britaglobal.sharepoint.com/sites/projectplatform/_api/SP.UI.ApplicationPages.ClientPeoplePickerWebServiceInterface.clientPeoplePickerSearchUser with QueryText test@test.com and MaximumEntitySuggestions:1. This API returns the Admin account because the admin account has test@test.com as OtherMails
