Mocking OAuth not working since 2.0.9

[langemeijer]

Since the oauth 2.0.9 I cannot mock (using phpunit) the OAuth class anymore. This worked using 2.0.7. I'm on latest PHP 8.3.

To Reproduce
This test succeeded with 2.0.7 and breaks with 2.0.9:

use PHPUnit\Framework\Attributes\Group;
use PHPUnit\Framework\Attributes\Test;
use PHPUnit\Framework\TestCase;

#[Group('unit')]
final class AuthorizationTest extends TestCase
{
    #[Test]
    public function minimalTestCase(): void {
        $consumerKey = 'ajkshjdng';
        $consumerSecret = 'asdhj3h4h34j';

        $oauth = $this->getMockBuilder(OAuth::class)
            ->setConstructorArgs([$consumerKey, $consumerSecret])
            ->getMock();

        $oauth
            ->method('getRequestToken')
            ->with()
            ->willReturnMap(
                [
                    ['fakeurl.org', null, ['oauth_token' => 'liajsdjwiu34', 'oauth_token_secret' => 'asdfhhherwer3']],
                ]
            );

        $tokenData = $oauth->getRequestToken('fakeurl.org');

        self::assertEquals('liajsdjwiu34', $tokenData['oauth_token']);
        self::assertEquals('asdfhhherwer3', $tokenData['oauth_token_secret']);
    }
}

Wouldn't see a reason why:
2.0.7...HEAD
