What steps will reproduce the problem?
(1) Enable Scroll Anchoring in About:flags
(2) Visit a vox.com article page (e.g. http://www.vox.com/policy-and-politics/2016/11/9/13572172/donald-trump-white-working-class). These pages leave black squares as placeholders for images in the article, and only load them once they are on screen (which is a bit weird)
(3) Scroll to show one of the black squares, and then continue scrolling so it is off screen at the top of the viewport before the image loads.

What is the expected result?

When the image loads, the page does not appear to scroll, due to scroll anchoring.

What happens instead?

When the image loads, the page scrolls by quite a bit. It is actually much WORSE with scroll anchoring on than off.
