[Bug]: Headless mode ignores arguments like "ignoreDefaultArgs". works only in headful mode.

[hschn]

Version

1.49.0

Steps to reproduce

based on this example, I want to ignore the default value for "notifications", which is "allow". I want to have the chrome-default (which is "ask")

this is my code:

const context: BrowserContext = await chromium.launchPersistentContext('./lpc',{
        ignoreDefaultArgs: ['--notifications'],
        headless: true,
    });

if I switch "headless" to false, everything works as expected and the value for "notifications" has "Ask (default)"

Expected behavior

settings for "notifications" have the value "Ask (default)

Actual behavior

settings for "notifications" have the value "Allow"

Additional context
