I just successfully upgrade my Magento v2.4.1 to v2.4.4, there is a problem when a new customer created, after successfully receive the confirmation email and click the confirmation link, The customer does not automatically logged in, instead it will be redirected to the customer/account/login page. Before upgrade to v2.4.4 it will be redirected to the customer/account page successfully, there is also a strange behaviour in this page login page, when i click log in after filling the form, there is an Invalid form key error error message
