Accessing stream on the interface Yiisoft\Yii\Debug\Helper\StreamWrapper\StreamWrapperInterface suggest that you code against a concrete implementation. How about adding an instanceof check?

        fwrite($handle, '1234567890');

        fseek($handle, 0);

        $firstElement = fread($handle, 2);
        $secondElement = fread($handle, 2);

        $this->assertNotSame($firstElement, $secondElement);

        fseek($handle, 0);

        $this->assertEquals($firstElement, fread($handle, 2));

        $proxy->stream_seek(0);
        $this->assertEquals($firstElement, fread($handle, 2));
    }
}
