BREAKING - File upload doesn't work with 2.1.0 release

[VikramTiwari]

Steps to reproduce

Tell us about your environment:

• Puppeteer version: 2.1.0
• Platform / OS version: any
• URLs (if applicable): any which shows a file input dialog box
• Node.js version: ~12

What steps will reproduce the problem?

• Run following script

const puppeteer = require("puppeteer");

(async () => {
	const browser = await puppeteer.launch({ headless: false });
	const page = await browser.newPage();
	await page.goto("https://cgi-lib.berkeley.edu/ex/fup.html", {
		waitUntil: "networkidle2"
	});
})();

• Click on the "choose file" button

Expectation: A file chooser dialog will appear
Result: Dialog box doesn't appear
End issue: Any upload that requires file chooser dialog breaks.
Possible reason: New changes with #5196

NOTE: It works fine with 2.0.0 release.

Possible reason: New changes with #5196

jsHandle.uploadFile is not used in your example, so it's not likely to be related to #5196, but rather to the upstream changes in https://chromium-review.googlesource.com/c/chromium/src/+/1935410.

I've filed this upstream: https://bugs.chromium.org/p/chromium/issues/detail?id=1047107 Thanks for the report!

@mathiasbynens
I have a question about the current status.
I'm facing this problem in the library that uses puppeteer.
It seems related PR (#5369 ) has already been merged, are you going to release the fixed version (v2.1.1?) soon?

Im finding the jsHandle.uploadFile is still failing in 2.1.1 is this related or a different issue?

I wanted to integrate Puppeteer 2.1.1 but I see that fileUpload still doesn't work:
