Thanks for taking this. Do you plan to revert r570135? Could  issue 856566  have the same root cause?
https://chromium-review.googlesource.com/c/chromium/src/+/1114353 should fix this. I can look at  issue 856566 ; the problem here was javascript executing faster than a CSS transform, but an iframe might cause the same problem

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/0d1ee6c47edb92525b9b092d65bf5d97e23454d4

commit 0d1ee6c47edb92525b9b092d65bf5d97e23454d4
Author: James Wallace-Lee <jamwalla@chromium.org>
Date: Wed Jun 27 17:13:02 2018

Deflake DumpAccessibilityTreeTest.AccessibilityTransform

End the test when the CSS transform is reflected in the dump, rather
than by using a separate label.
