box-shadows on <button> elements render shadows as squares sometimes

Reported by mattf53...@gmail.com, Jul 8 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3152.0 Safari/537.36

Example URL:
https://bcm-company.github.io/octohydra/#contactus

Steps to reproduce the problem:
1. Make a button with border-radius: 50%
2. Add a box-shadow with a blur (I think).

What is the expected behavior?
The shadow renders in the shape of the element, in a circle.

What went wrong?
Instead, the browser renders it as a square, including blur.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No 

Did this work before? Yes 59.0.3071.86 (Might work in later, but not 61.0.3152.0)

Does this work in other browsers? Yes

Chrome version: 61.0.3152.0  Channel: canary
OS Version: 10.0
Flash Version: Shockwave Flash 26.0 r0

An interesting thing is that the blur isn't rendered, and instead is included in the shadow box.

Tested on  Canary #61.0.3152.0 on Windows 10 & Mac 10.12.5 and able to reproduce the mentioned behavior. 

Using the per revision bisect providing the bisect results,

Good Build: 61.0.3151.4 (Revision: 484781).
Bad Build: 61.0.3152.0 (Revision: 485105).

You are probably looking for a change made after 485071 (known good), but no later than 485072 (first known bad).

I think it is similar. Thanks.
Also, this isn't a high priority problem, since most people use Chrome stable.
