Unwarranted reflow mitigation

"The new Scroll Anchoring feature in Chrome seems to completely wreck Google Image Search. Images near the top of the results are OK, but if you scroll down a bit and then click an image, Chrome seems to jump to a completely random place in the list and you have to scroll manually to find the image you clicked. This is affecting lots of other people as well (e.g. https://productforums.google.com/forum/#!topic/chrome/LNGBzMlzuPM and also confirmed via random people on Twitter). After disabling Scroll Anchoring, the problem seems to have gone away."
