Issue with page: https://symfony.com/doc/current/security/expressions.html

In https://symfony.com/doc/current/security.html#checking-to-see-if-a-user-is-logged-in-is-authenticated-fully docs are provide information, that IS_AUTHENTICATED_ANONYMOUSLY attribute are granted for anon. tokens and fully authenticated.

IS_AUTHENTICATED_ANONYMOUSLY: All users (even anonymous ones)

On https://symfony.com/doc/current/security/expressions.html we see, that is_anonymous() expression are the same as IS_AUTHENTICATED_ANONYMOUSLY.

is_anonymous
Equal to using IS_AUTHENTICATED_ANONYMOUSLY with the isGranted() function.

But in code we can see, that is_anonymous() returns true only for anon. tokens.

return $variables['trust_resolver']->isAnonymous($variables['token']);
