Touchpad: "keyup" is fired when no keyup happens

Reported by ivan.kuc...@gmail.com, Jan 20 2018

Issue description

UserAgent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36

Steps to reproduce the problem:
1. Go to https://jsfiddle.net/tk4s9y4o/
2. Press Alt, put two fingers on the touchpad, move them and put them away (while still holding Alt)

What is the expected behavior?
As soon as your fingers leave touchpad, Chrome fires the "keyup" event with key:"Alt"

What went wrong?
The "keyup" should not be fired until some key is released.

Did this work before? N/A 

Chrome version: 63.0.3239.132  Channel: stable
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: Shockwave Flash 28.0 r0

You made a mistake in step 2. : you have to move your fingers on a touchpad at least a bit before releasing them (not just put and release).

BTW. it could be some Windows- or Windows7-, or maybe even Lenovo-related problem :(

I've tried this on a Windows 10 Surface book as well and it appears to work fine. This is likely some software that is doing gestures via installed apps/drivers. The key events come from the OS so I doubt there is much we can do.

Do you have any additional software installed that does gesture recognition on the laptop?
I have a ThinkPad UltraNav driver, from Alps Electric. It works the same in Firefox, too, so I guess it is not your fault. You can close it now.
