1px lines disappear on 80, 90% zoom levels

Reported by char...@masterdynamic.com, May 24 2017

Issue description

UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36

Steps to reproduce the problem:
1. Visit this jsfiddle in chrome: https://jsfiddle.net/4jep9qp0/
2. Zoom out the browser window view (cmd +, cmd -)

What is the expected behavior?
It is expected that lines remain visible at 80 to 90% zoom level. I don't expect them to be visible at very small levels (30% below)

My preliminary research suggests that chrome doesn't render subpixel values on zoom, but I have this line set to 1px exactly. 

What went wrong?
The line does not display consistently across zooms greater than 50%. 

Did this work before? N/A 

Chrome version: 58.0.3029.110  Channel: stable

Able to reproduce this issue on Mac 10.12.4, Win-10 and Ubuntu 14.04 using chrome reported version #58.0.3029.110 and latest canary #60.0.3109.0.

This is a non-regression issue as it is observed from M30 old builds. 

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

Thanks...!!

We sometimes end up with a 0-sized background rect when we snap under zoom. It's not clear how to fix this.

On linux I lose it at 90% but it's there at every other zoom size.
