-webkit-backface-visibility: hidden causes problems with column-layout

Reported by flxw...@googlemail.com, May 4 2018

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36

Example URL:
https://jsfiddle.net/904j1mjk/

Steps to reproduce the problem:
1. Go to https://jsfiddle.net/904j1mjk/ and view the example with three columns
2. Try to click on a link in the second or third column

What is the expected behavior?
Links in the sceond and third column should be clickable, too.

What went wrong?
Chrome has a problem with the column-layout when -webkit-backface-visibility: hidden; is set for all elements.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No 

Did this work before? N/A 

Does this work in other browsers? Yes

Chrome version: 66.0.3359.139  Channel: stable
OS Version: 10.0
Flash Version: 

This problem incidently occured an our website in the last few days. I am sure that this must be a bug of the newest Chrome version, because this problem never happened before on this page and there where no styling changes at all in the last months.
Firefox doesn't have this issue.

This looks like an issue in hit testing so over to paint/input.

Bisects to this:

This is a P1 stable regression.

Actually, we might live with this as it only affects backface-visibility with multi-column,
This is like  bug 839008 , but the CL didn't fix this bug :(

I made a mistake when verifying if the CL for  bug 839008  fixed this bug. It's actually fixed and merged.
