DevTools: Network.responseReceived is sometimes never dispatched

Project Member Reported by lushnikov@chromium.org, Sep 12 
Chrome Version       : 71

------------------------------------------
TL;DR: Network.responseReceived is sometimes never received, but both Network.requestWillBeSend and Newtork.loadingFinished are.
------------------------------------------

(Originally reported in puppeteer: https://github.com/GoogleChrome/puppeteer/issues/2888)

NOTE: This repro relies on a hosted website that might be taken down anytime; but that's the
only one I have).

1. Install puppeteer v1.7.0:

  $ npm install puppeteer@1.7.0

2. Use the following puppeteer script:

const puppeteer = require('puppeteer');

(async() => {
  const browser = await puppeteer.launch({headless: false, dumpio: true});
  const page = await browser.newPage();
  await page.goto("https://vault.rosx.technology");
  await page.click("header button");
  await page.waitForSelector('input[name="pf.username"]');
  await page.type('input[name="pf.username"]', "ertbnm+6pbwenc1esl3s@sharklasers.com");
  await page.click("#els-continue");
  await page.waitForSelector('input[name="password"]');
  await page.type('input[name="password"]', "123qwe");
  await page.click('button[type="submit"].els-primaryBtn', {delay: 1000});
  await page.waitForNavigation();
  await page.waitForSelector("h1");
  await browser.close();
})();


3. Run the script using protocol session output:

  $ DEBUG=*session node script.js

4. Notice the exception in node.js: "response is null". This happens because Network.responseReceived
event is never received for certain event, but both Network.requestWillBeSent and Network.loadingFinished are dispatched.



This happens because blink::InspectorNetworkAgent::DidReceiveResourceResponse is called *twice* for the
request in question, both times with empty resource:
- first time via blink::FrameFetchContext::DispatchDidReceiveResponse
- second time via blink::RawResource::ResponseReceived

As I figured from the DidReceiveResourceResponse, we don't dispatch empty responses (because why would we?).


=================================================

For the record, the two stack traces:
