--enable-features=WebContentsForceDark - Doesn't work in headless mode.

I'm new to playwright (.net), forgive me if I'm doing something wrong. I'm trying to take a screenshot in dark mode, using a headless browser, but everything I tried just doesn't work for me. The closest I got was using a non-headless, which seemed to work. I tried all the colorscheme:dark options using PageEmulateMediaOptions and BrowserNewContextOptions. This didn't work for me. The arg, works, but only in non-headless mode. Their are some differences

var browser = await playwright.Chromium.LaunchAsync(new LaunchOptions { Headless = true, Args = new string[] { "--enable-features=WebContentsForceDark" } });

I feel like I'm just missing something easy..

This thread is trying to answer question "How can I take a screenshot in dark mode using a headless browser in playwright (.net)?"
