--- Comment #9 from Simon Fraser (smfr) <simon.fraser at apple.com> ---
After lots of debugging, I think the iOS difference is due to differences in timer slop, and how we drive rendering updates with UI-side compositing. I did file bug 244276, and I'll adjust the test to call `setSpeculativeTilingDelayDisabledForTesting(true)` to make sure that doesn't introduce flakiness.
