Selenium php-webdriver忽略所有参数和扩展名

Question

UPDATED: I will leave the question open in case someone can explain what I was doing wrong. I didn't fix the issue, but I achieved result after switching from "selenium-hub + chrome node" to "standalone chrome" image in docker-compose.yaml

---

I'm using facebook/php-webdriver to run Chrome test with Selenium. Here is the simple code example:

I'm using SeleniumHQ/docker-selenium to run Selenium. So docker-compose.yaml is like:

...
    selenium-hub:
        container_name: selenium-hub
        image: selenium/hub:latest
        ports:
            - "4444:4444"
    chrome:
        container_name: chrome
        image: selenium/node-chrome:latest
        volumes:
            - /dev/shm:/dev/shm
        depends_on:
            - selenium-hub
        environment:
           - HUB_HOST=selenium-hub
           - HUB_PORT=4444
           - SCREEN_WIDTH=1280 
           - SCREEN_HEIGHT=800
           - SCREEN_DEPTH=24
        entrypoint: bash -c 'SE_OPTS="-host $$HOSTNAME" /opt/bin/entry_point.sh'
...

PHP code:

        $options = (new ChromeOptions())
            ->addArguments([
            '--window-size=640x480',
            ]);
        $capabilities = DesiredCapabilities::chrome();
        $capabilities->setCapability(ChromeOptions::CAPABILITY, $options);
        $driver = RemoteWebDriver::create('http://selenium-hub:4444/wd/hub/', $capabilities, 5000);
        $driver->get('chrome://version/');
        header("Content-Type: image/jpeg");
        echo $driver->takeScreenshot();
        $driver->quit();

For some reason params in addArguments() doesn't have any impact - the outcome is always the same no matter what was set in the method addArguments(). It is always something like this

Whatever I'll put to addArguments() nothing will change.

Any ideas are appreciated.
