High resolution low-latency touchpad scrolling lost in Chrome 52 (worked in 51)

Reported by vanv...@gmail.com, Jul 22 2016

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.82 Safari/537.36

Steps to reproduce the problem:
1. DISABLE fake "Smooth Scrolling" in chrome://flags as it causes high latency.
2. Restart Chrome
3. Load news.google.com
4. Scroll with two fingers on a touchpad

What is the expected behavior?
High resolution low-latency scrolling, such that you have the precision to scroll one pixel at a time if you're careful.

What went wrong?
It stopped working in Chrome 52. In Chrome 52 it has reverted to jumping by whole mouse wheel-style ticks, like in versions <50.

AFAIK this only ever worked correctly in Chrome 51, possibly by accident.

Did this work before? N/A 

Chrome version: 52.0.2743.82  Channel: stable
OS Version: Ubuntu 16.04
Flash Version: 

You had a killer feature, possibly by accident. Please bring it back!

Don't have Linux touchpad laptop to check and confirm this. Adding proper label for someone from the respective team to have a look at this.

Cc'ing 	bokan@ from  Issue 616308  for more inputs on this and confirmation if this is being worked in  Issue 384970 .

I'm seeing this behaviour as well. As far as I can remember, high resolution smooth scrolling has worked for me for the last few versions of Chromium on Linux.
I can confirm that this happens to me as well on Arch Linux/4.6.4-1.

It was intentionally turned off as it was broken in certain hardware configurations. There was no way for an end user to turn it off so it made life really miserable for a small population.

We're going to turn it back on for M54 with a flag to disable until we can hammer out all the issues. Sorry for the inconvenience.
