Mine (7064677daf7d84d442fd60124d59f6d6a618638e) is basically a no-op change,
so I think this seems a false alarm to me at this point.

Comment 5 by kolos@chromium.org, Jan 14 2018 

This is probably my CL.

(Moving over to Maxim and removing me as I don't think the changed test expectation could have any impact.)
