Failed_Login_Attempts and Password_lock_Time not updating mysql.user.account_locked column

In Percona MySQL 8.0.33, we enabled the following on the users
Failed_login_attempts 5
password_lock_time UNBOUNDED

The functionality works fine as after 5 failed attempts, it returns the error “ERROR 3955 (HY000): Access denied for user ‘abcdef’@‘localhost’. Account is blocked for unlimited day(s) (unlimited day(s) remaining) due to 5 consecutive failed logins.” But it is not updating the column account_locked in mysql.user table.
Also, it does not show the status in SHOW CREATE USER…

We also enabled Connection Control Plugins.

Are we missing any setup?

Any update on this is highly appreciated.
