I'm using puppeteer-sharp and here is my browser creation code 

Browser browser = await Puppeteer.LaunchAsync(new LaunchOptions {
    Headless = false,
    Args = new[] {
    "--js-flags=\"--harmony\"",
    "--flag-switches-begin",
    "--enable-features=javascript-harmony",
    "--enable-features=ExperimentalJavaScript",
    "--enable-javascript-harmony",
    "--flag-switches-end",
  }
});

from that answer I read that --harmony V8 argument is enough for the needed flag to be enabled, but it isn't.

Although the arguments are passed

Flag is still not enabled

P.S. --enable-features=ExperimentalJavaScript, --enable-features=javascript-harmony and --enable-javascript-harmony I added myself making them by analogy to 1 2, not sure if these are correct usages (didn't found any documentation on this)

I am also unable to set flags when running google-chrome from command line google-chrome-stable --args --flag-switches-begin --enable-features=javascript-harmony --flag-switches-end
