puppeteer: [Bug]: headless: true renders page as white.

Bug expectation

I expected the page to be rendered, but it was rendered as a white screenshot. Problem page: https://theopenweb.info

I tried on 3 pages, a popular page, the problem page, a page on the same domain as the problem page. Only the problem page has the issue. The issue only happens when headless is true.

This page has had similar issues in a few libraries using puppeteer. This page seems to have indexing issues on Google. Does Google use puppeteer in headless mode for indexing?

Minimal, reproducible example

import puppeteer from 'puppeteer'; // TS/ESM are all supported.
// const puppeteer = require('puppeteer')

(async () => {
// const url = 'https://news.google.com/news/'
const url = 'https://theopenweb.info'
// const url = 'https://theopenweb.info/apps/'

async function test(headless = false) {
  const browser = await puppeteer.launch({ headless });
  const page = await browser.newPage();
  await page.goto(url);
  await page.screenshot({path: (headless ? 'headless_' : '') + 'screenshot.png', fullPage: true});
  await browser.close();
}
await test(true) // headless
await test(false) // not headless
})();

// SAME

// "puppeteer": "19.7.3"
