Single-click on Pixel 2 Touchpad results in 2 rapid clicks

Project Member Reported by jdries3@google.com, Jan 12 2017

Issue description

Chrome Version       : 56.0.2924.53
OS Version: 9000.50.0
URLs (if applicable) :
Other browsers tested:
  Add OK or FAIL after other browsers where you have tested this issue:
     Safari 5:
  Firefox 4.x:
     IE 7/8/9:

What steps will reproduce the problem?
1. Use CrOS on Pixel 2
2. Open any Google App (Spreadsheets, Calendar, etc.)
3. Tap on elements with Touchpad

What is the expected result?
Single Tap results in single click events.

What happens instead of that?
Single Tap results in two click events in rapid succession. For example, clicking on a Calendar event should bring up the info tab for the event, but instead the full "edit event" page is loaded. Or in Google Sheets, single tap on a tab will result in edit/renaming the tab instead of just selecting it.

Please provide any additional information below. Attach a screenshot if
possible.

Screenshot provided in ALT-SHIFT-I feedback.

Andrew, is this something you've heard of? I assume tap-to-click is enabled.

Joseph, does this happen everywhere or just when you're using various Google apps?

Hi,

Tap-to-Click is NOT enabled. Neither are any accessibility settings. The
only thing that I have enabled WRT the Touchpad is Australian Scrolling.

Difficult to say. I can test something if you know of a non-Google
application that would accept & process double-clicks rather than single
clicks.

What do you see in the JS console if you load https://jsfiddle.net/LLt5qj3y/, click "Run", and then single-click in the bottom-right frame?

(To debug this, I'm guessing that Andrew or someone else will need to check the touchpad events in the feedback report, though.)

Summary: Single-click on Pixel 2 Touchpad results in 2 rapid clicks (was: Single Tap on Pixel 2 Touchpad results in 2 rapid clicks)
And to clarify, you're actually pushing the touchpad down until it clicks and not just tapping it, right?

Hi,

Here's the output:

(index):45 mousedown
(index):46 mouseup
(index):47 click
(index):45 mousedown
(index):46 mouseup
(index):47 click
(index):48 dblclick

Also, I noticed that the 2 clicks happen on the Hangouts Chrome Plugin (I
have transparent UI enabled). It also happens on the 3-dots settings menu
in the Chrome browsing window. And also the ChromeOS Taskbar
Time/Network/Battery/User menu. Mean that I tap on those areas, and the
menu flashes open and then immediately closed.

Re #4, I am actually pushing the touchpad down until it clicks. I do not have touch-to-tap enabled. These are physical presses that register.
