What happened?

I'm working on a Selenium script to automate browser tasks, and I've run into an issue regarding the DevTools message. When I use the --headless option, the following message keeps appearing in the console:

"DevTools listening on ws://127.0.0.1:51481/devtools/browser/505e7f66-fd69-494b-a733-0cce438dec53"

However, the message successfully disappears when I remove the --headless option.

How can we reproduce the issue?

from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_experimental_option("excludeSwitches", ['enable-logging'])
options.add_argument("--log-level=3")
options.add_argument("start-maximized")
options.add_argument("--headless")
driver = webdriver.Chrome(options=options)
input("")

Relevant log output

DevTools listening on ws://127.0.0.1:51481/devtools/browser/505e7f66-fd69-494b-a733-0cce438dec53
