Content-Download in Network Timing possibly is wrong

Reported by mora...@gmail.com, Mar 26 2018

Issue description

UserAgent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.186 Safari/537.36

Steps to reproduce the problem:
1. Open DevTools > Network
2. Open https://sbis.ru/tariffs?tab=ereport
3. Look at waterfall on network tab
4. Do same in Firefox/Safari/Fiddle

What is the expected behavior?
We have nearly the same content-download time for all resources

What went wrong?
Content-Download time for Chrome is much bigger 

Did this work before? N/A 

Chrome version: 64.0.3282.186  Channel: n/a
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: 

I can guess after some investigation that are different factors that affects content-download time:
1. http2 priority
2. slow disc cache reading/writing
3. heavy js code

I have tried comparing Chrome DevTools (Chrome 68) against Firefox and did not find any evidence of Chrome being clearly slower then FF. I saw large differences that went both ways - likely caused by network.

Chrome is not slower then Fx. Content-Download times are different in Chrome and in Fx for the same request, that's the problem. I've just opened the same page with both browsers as an example. Pls, look at both screenshots in attachment.
