Steps to reproduce the problem:
1. I'm trying to run some tests using headless mode so I set "intl.accept_languages" to "pl, fr, ru, it" and also added argument "--headless"
2. When the request comes from browser to server I see that value "accept_languages" in request header does not exist.

When I try to run the same test without headless mode accept_languages in header looks as expected.

What is the expected behavior?
headless mode should provide previously set accept_languages

What went wrong?
missing accept_languages in headless mode

Did this work before? No

Here's how i make configuration:

SeleniumWebDriver.Bootstrap(SeleniumWebDriver.Browser.Chrome);
var containerRegistration = FluentSettings.Current.ContainerRegistration;

FluentSettings.Current.ContainerRegistration = container =>
{
	containerRegistration(container);

	var driverPath = EmbeddedResources.UnpackFromAssembly("chromedriver.exe", Assembly.GetAssembly(typeof(BaseTestConfigurator)));
	driverPath = Path.GetDirectoryName(driverPath);

	if (_browserChromeOrderCulture != null)
	{
		chromeOptions.AddUserProfilePreference("intl.accept_languages", $"{_browserChromeOrderCulture}");
	}

	if (TestsEnv.UseChromeHeadlessMode)
	{
		chromeOptions.AddArguments("no-sandbox", "headless", "disable-gpu");
	}

	container.Register<IWebDriver>((c, o) => new ChromeDriver(driverPath, chromeOptions));
};
