How to set the host header in playwright

I have a need to be able to change the host header for a url. I've tried setting extra headers but I keep getting an invalid argument error.

from playwright.sync_api import sync_playwright    

def get_title():
    with sync_playwright() as playwright:

        browser = playwright.chromium.launch(headless=True)
        context = browser.new_context(
            user_agent="testing",
        )
        context.set_extra_http_headers({"host": "example.com"})
        page = context.new_page()
        page.goto(url="http://111.222.333.444", wait_until="domcontentloaded")

        title = page.inner_html(selector="title")

        context.close()
        browser.close()

        return title

Setting the header to the page or the context give the same error. Is it possible to set the host header with playwright?

Chromium will not allow you to override the Host header. I presume this is because Host is something the browser manages internally. Source.

Why do you want to modify this header?
