css property "touch-action: none" does not always prevent default browser pinch-to-zoom

Reported by blumer.a...@gmail.com, Feb 13 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36

Steps to reproduce the problem:
1. Open the attached test case html page
2. On a touch-enabled device (tested on a windows pc and an android phone) touch the display with two fingers and perform a pinch-to-zoom gesture. As expected, nothing should / will happen.
3. Lift ONE finger off the screen and put if back down.
4. Again, perform a pinch-to-zoom gesture. Against expectations, this time the default browser zooming should kick in.

What is the expected behavior?
Both in step 2 & 4, no default browser pinch-to-zoom should happen. 

What went wrong?
In step 4, pinch-to-zoom happens, even though the css property "touch-action: none" was specified.

Did this work before? N/A 

Does this work in other browsers? Yes

Chrome version: 56.0.2924.87  Channel: stable
OS Version: 10.0
Flash Version: Shockwave Flash 24.0 r0

I also tested this on the same device using Microsoft's Edge browser which does not exhibit this behaviour.

 
I might have missed adding the test case mentioned above

Status: Untriaged (was: Unconfirmed)
Tested the issue on chrome Stable #56.0.2924.87, Canary 58.0.3012.0 in Windows 10.0 and was able to reproduce the issue.

This is a Non-Regression issue since seeing this from M30 #30.0.1549.0, Making the status to Untriaged so that the issue would get addressed.

Note : Unable to test the issue in MAC 10.12 and Linux Ubuntu 14.04 due to hardware dependency.

Thank you.

Sounds more like an input issue than CSS.

This is a duplicate of 662047 which the fix was merged into the M55 branch but not the M56 branch. It is correct in M57.
