Pull-to-refresh causes `position: fixed` headers to move a few pixels down from `top: 0`, creating a gap

Reported by ja...@lengstorf.com, Apr 28 2016 
Steps to reproduce the problem:
1. Open a site with an element that is `position: fixed; top: 0` (I put up http://chromebug.herokuapp.com/ to demonstrate this)
2. Do a pull-to-refresh motion, but DO NOT actually refresh the page
3. Scroll down and the fixed element will now have a gap above it, even though it's set to `top: 0`

What is the expected behavior?
The fixed element should always remain at `top: 0`.

What went wrong?
The position of the fixed element, despite the CSS still instructing `top: 0`, is nudged down the page by 1–5px.

Did this work before? N/A

I was unable to find a bug filed after this post, however.
