Status: WontFix (was: Assigned)
These are on master=ChromiumPerfFyi, so should be ignored despite the scary amount of regressions.

Pasted from the SpeedInfra chat:
Likely related to the catapult roll:
  https://chromium.googlesource.com/external/github.com/catapult-project/catapult.git/+log/04dd47e541e2..30ce231266c6
Ned's changes in that roll changed the test

Bisect failed: http://build.chromium.org/p/tryserver.chromium.perf/builders/winx64intel_perf_bisect/builds/1148
Failure reason: the build has failed.
Additional errors:
The metric was not found in the test output.
Either of the initial "good" or "bad" revisions failed to be tested or built.
