White flash before new tab page with extensions (macOS)

Reported by web.acce...@gmail.com, May 11 2018

Issue description

UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36

Steps to reproduce the problem:
1. Install the attached extension
2. Open a new tab
3. Notice a white background/flash before the rendering starts

What is the expected behavior?
No white flash / white background before the page is rendered at least for extensions / locally accessible new tab pages.

What went wrong?
Visible white background before the page is rendered.

Did this work before? N/A 

Chrome version: 65.0.3325.181  Channel: n/a
OS Version: 
Flash Version: 

This bug is a follow-up for  issue 834449 : https://bugs.chromium.org/p/chromium/issues/detail?id=834449

A regression which is now marked as fixed for Linux and Windows. 
As mentioned in comments #11 and #32:
* The problem is *not* fixed for macOS (#32)
* For macOS the problem exists 'forever' at least since M-60 (#11)

So as suggested in comment #45 I filed this separate bug report to address the issue.
I cannot provide any test results myself, because I do not own a Mac. So it would be awesome if someone else could confirm that.

Status: Untriaged (was: Unconfirmed)
Able to reproduce the issue on Mac 10.13.3 using chrome stable version #64.0.3282.186 and latest canary #68.0.3430.0.
This is a non-regression issue as it is observed from M60 old builds. 

Hence, marking it as untriaged to get more inputs from dev team.

Thanks...!!

Please try on Chrome 68 Canary -- flashes at navigation have been addressed recently.

The flash appears when opening a new tab and not during navigation.
