request.headers() does not give all headers that are used when making the request

const browser = await puppeteer.launch();
const page = await browser.newPage();

page.on('request', async (request) => {
  await request.headers();
});

await page.goto('http://gajus.com');

just gives:

'upgrade-insecure-requests': '1',
'user-agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) HeadlessChrome/79.0.3945.0 Safari/537.36',
'sec-fetch-user': '?1'

whereas the actual headers include additional headers such as: accept, accept-language and accept encoding.
