Would that error be reported by openssl_error_string()?

Description:
------------
According to the documentation, mysqli::$connect_error returns the last error message string from
the last call to mysqli_connect(). NULL is returned if no error occurred.
However, if the underlying connection error is related to SSL, mysqli::$connect_error remains NULL
which is incorrect.
The reproduction script tries to connect to a MySQL server running in a https://hub.docker.com/_/mysql container and relies on the
fact that the CN in the autogenerated server certificate doesn't match its hostname.
The same problem is reproducible with literally any SSL error.
Test script:
---------------
<?php
$conn = mysqli_init();
$conn->ssl_set('client-key.pem', 'client-cert.pem', 'ca.pem',
'', '');
if (!$conn->real_connect('127.0.0.1', 'root', '',
'mysql')) {
var_dump($conn->connect_error);
exit(1);
}
Expected result:
----------------
$conn->connect_error contains a string with an error message.
Actual result:
--------------
Warning: mysqli::real_connect(): Peer certificate
CN=MySQL_Server_8.0.18_Auto_Generated_Server_Certificate' did not match expected
CN=127.0.0.1' in /home/morozov/mysqi-tls.php on line 7
