We have implemented the CHIPS(Cookies Having Independent Partitioned State) solution on our website by adding the partition attribute. It works fine when a user logs in for the first time. However, if a user is already logged in and we attempt to modify the existing cookie by adding the partition attribute or if we try to log in another user without logging out the current user, the cookie is supposed to be overridden. Instead, we observe two cookies with the same name and value, one with the partition key and one without. This seems to be an issue with the beta version, or is it the expected behavior? For other attributes, the cookie is correctly overridden, but with the partition attribute, this unusual case occurs.
