`page.pdf()` does not resolve#53

- Deno version: 1.20.5 (release, x86_64-pc-windows-msvc) - Platform / OS version: Windows 10.0.25126 When I run the [hackernews.ts](https://github.com/lucacasonato/deno-puppeteer/blob/main/examples/hackernews.ts) example – ```ts import puppeteer from 'https://deno.land/x/[email protected]/mod.ts'; const browser = await puppeteer.launch(); const page = await browser.newPage(); await page.goto("https://news.ycombinator.com", { waitUntil: "networkidle2" }); console.log('before'); await page.pdf({ path: "hn.pdf", format: "a4" }); console.log('after'); await browser.close(); ``` a file at `./hn.pdf` is created, but it appears to be empty, and `await page.pdf({ path: './example.pdf' });` never resolves. There are no error message, and the [default timeout](https://github.com/puppeteer/puppeteer/blob/v14.1.1/docs/api.md#pagepdfoptions) after 30 seconds also does not occur. The same code setup does work on my system in NodeJS with Puppeteer v14.1.1 and Chromium 991974, but [#4136](https://github.com/puppeteer/puppeteer/issues/4136) in the Puppeteer issues describes something similar, that seems to have been fixed by version 1.13.0.
