Issue descriptionUserAgent: 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.

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. |
