Why does headless mode have no effect

[rew1nter]

Rod Version: v0.116.2

The code to demonstrate your question

Headless(true|false) has no effect on the browser here. The browser is always shown

package main

import (
	"github.com/go-rod/rod"
	"github.com/go-rod/rod/lib/launcher"
)

func main() {
	// make sure target browser is closed
	path := "/usr/bin/chromium"
	// launch installed browser
	wsURL := launcher.NewUserMode().Bin(path).Headless(true).MustLaunch()
	// connect to the browser
	browser := rod.New().ControlURL(wsURL).MustConnect().NoDefaultDevice()

	browser.MustPage("http://127.0.0.1:80/#")
}

What you got

The browser always shown

What you expect to see

The browser shown or hidden based on the flag

What have you tried to solve the question

You are probably using the last browser. UserMode is a raw mode, you literally have to manage everything, if you don't close the browser, it will remain open. In this mode, rod will not help you to close the browser.
