background-attachment not working properly on Mac without border-radius

Reported by klemen.k...@kream.io, Jan 30 2018 
UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.119 Safari/537.36

Steps to reproduce the problem:
1. Open the included index.html.
2. Observe the issue.
3. Uncomment border-radius property to fix the issue.

What is the expected behavior?
The div should have a shadow on top and bottom, dependent on scroll position. If I uncomment the border-radius (set it to non-zero, for example 0.0000001px), it will work as expected.

What went wrong?
Only the bottom shadow on the div is shown, regardless of scroll position.

Did this work before? Yes I found a comment stating that this was broken in 59 (maybe even earlier).

Does this work in other browsers? Yes

Chrome version: 64.0.3282.119  Channel: stable
OS Version: OS X 10.13.3
Flash Version: 

This only happens on macOS.

Reproduces on 66.0.3334.0 (Official Build) canary (64-bit) Mac.

Requesting bisect to determine revision that caused this issue.

Able to reproduce this issue on reported version 64.0.3282.119 and on latest canary 64.0.3334.0 using Mac Retina 10.13.1. 

Observations:
1. Issue is not seen in Non-Retina Mac 10.13.1.
2. Issue is not seen in Linux and Windows.
3. Issue is seen from M50[50.0.2661.0]

This issue is seen from M60. Hence considering this issue as Non-Regression, marking as Untriaged and removing Needs-Bisect.
