Why is the extension method ClaimsPrincipalExtensions.GetDisplayName returns claim preferred_username first

[mgrosperrin]

Hi all,
Do you know why the extension method ClaimsPrincipalExtensions.GetDisplayName in the project Microsoft.Identity.Web.TokenCache returns the value of the claim preferred_username first and not the claim http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name or name?
It is a little disturbing to have the login of the user as display name...
Thanks for your insights😄
