No, that CL only made changes to a test unrelated to this. If you increase the window a bit you'll see that the numbers are simply back to normal, and that they became worse a few versions back as part of nisse's cl:
https://bugs.chromium.org/p/chromium/issues/detail?id=639751

Nisse, is this change expected?

I'm having some difficulty correlating the graphs with commits. But lots of perf test graphs got bumps from my buggy cl. They're expected to get back to normal when I reverted it in https://codereview.chromium.org/2263183002/, and be unchanged with the reland https://codereview.chromium.org/2270723002/

Ok, I suggest closing this since the values are back to normal rather than regressing.
