Hi,
Unfortunately video with lossy codec doesn't help here. I cannot confirm that it isn't reproduced on the attached video due to compression artifacts. Also zooming inside Chrome doesn't help too because rendering is changed.

Could you please take a screenshot, save it as PNG and attached here?

Thank you for providing more feedback. Adding the requester to the cc list.

I've attached enlarged screenshot of my screen.
It is clearly seen that border has 3 px height.

Reproduced on Linux Mint with Chrome 65.0.3325.181 too.

The same page on the same machine:
Firefox - border is exactly 1 px
Chrome  - border is 2 px.

Please don't use zoom in browser. It changes rendering as I already wrote.

Open the attached page with zoom at 100% and don't change it.
Take screenshot and enlarge it in any graphical editor like Photoshop/GIMP/MSPaint.
Check that border isn't 1 pixel.

Thank you.

This is working as intended, I believe, in that we are drawing an antialiased border stroke.
