PMA_SSL_VERIFY is ignored

When connecting over TLS to proxysql using self-signed certificates, I set PMA_SSL_VERIFY to 0 because CN verification fails if an IP address is specified in PMA_HOST, but it did not work.
I started the container with the following variables.

PMA_HOST: "192.168.xxx.xxx"
PMA_PORT: "6033"
PMA_SSL: "1"
PMA_SSL_VERIFY: "0"
PMA_SSL_CA_BASE64: "self-signed CA file (BASE64 encoded)"

If $ssl_verifies[$i - 1] is not 1 in config.inc.php, the value of PMA_SSL_VERIFY seems to be ignored.

docker/config.inc.php

Line 145 in 24c2f1f

if (isset($ssl_verifies[$i - 1]) && $ssl_verifies[$i - 1] === '1') {

As a solution, I installed the following config.user.inc.php, which allows phpmyadmin to connect to proxysql, which uses self-signed certificates, over TLS.

config.user.inc.php

<?php
if ($_ENV['PMA_SSL'] && isset($_ENV['PMA_SSL_VERIFY'])) {
    for ($i = 1; isset($hosts[$i - 1]); $i++) {
        $cfg['Servers'][$i]['ssl_verify'] = $_ENV['PMA_SSL_VERIFY'];
    }
}
