CORS fail after setExtraHTTPHeaders

CORS fail after setExtraHTTPHeaders if you disable OOR-CORS(out-of-blink-cors) using below code, same code works puppeteer.launch({headless:false, launch: {args:[“–flag-switches-begin”, “–disable-features=OutOfBlinkCors”, “–flag-switches-end”]}});

any ideas?

Steps to reproduce

Tell us about your environment:

• Puppeteer version: 1.19.0
• Platform / OS version: Windows 10
• URLs (if applicable):
• Node.js version: v12.9.1

What steps will reproduce the problem?

/* node --experimental-repl-await */
const puppeteer = require('puppeteer')
const browser = await puppeteer.launch({headless:false})
const page = await browser.newPage()
await page.setExtraHTTPHeaders({'test':'aa'})
await page.goto('https://youtube.com')
/* F12 developer mode */

What is the expected result? CORS success regardless setExtraHTTPHeaders

What happens instead? CORS fail

Ran into the issue on 5.4.1 again and the '--disable-features=OutOfBlinkCors' workaround no longer mitigates the issue.
