Runtime options set in composer.json are not loaded

[starred-gijs]

Im testing the new BrefRuntime package and I noticed something. Im still figuring out how exactly it works, but this is the scenario:

I have a runtime option set in composer.json 'extra.runtime.options'

{
    "require": {
        "...": "..."
    },
    "extra": {
        "runtime": {
            "use_putenv": true
        }
    }
}

This will generate the autoload_runtime.php with 1 extra line

$runtime = $_SERVER['APP_RUNTIME'] ?? $_ENV['APP_RUNTIME'] ?? 'Symfony\\Component\\Runtime\\SymfonyRuntime';
$runtime = new $runtime(($_SERVER['APP_RUNTIME_OPTIONS'] ?? $_ENV['APP_RUNTIME_OPTIONS'] ?? []) + [
  'use_putenv' => true, // <<<=== THIS LINE IS ADDED
  'project_dir' => dirname(__DIR__, 1),
]);

But I think the part of the file is not loaded because $_SERVER['SCRIPT_FILENAME'] is empty (please confirm this)

if (true === (require_once __DIR__.'/autoload.php') || empty($_SERVER['SCRIPT_FILENAME'])) {
    return;
}

And in HandlerResolver the BrefRuntime is created without the use_putenv option:

            // Use the Symfony Runtime component to resolve the closure and get the PSR-11 container
            $options = $_SERVER['APP_RUNTIME_OPTIONS'] ?? [];
            if ($projectDir) {
                $options['project_dir'] = $projectDir;
            }
            $runtime = new BrefRuntime($options);

---

The workaround is to use the other way of setting options, in public/index.php:

<?php

use App\Kernel;

$_SERVER['APP_RUNTIME_OPTIONS'] = [
    'use_putenv' => true,
];

require_once dirname(__DIR__).'/vendor/autoload_runtime.php';

return function (array $context) {
    return new Kernel($context['APP_ENV'], (bool) $context['APP_DEBUG']);
};

Not sure if this is a feature this bridge would like to support, but if not, a warning message in the docs would be nice :)
