+dtu can we re-run this after fixing bisect to patch over breakages?

😿 Pinpoint job stopped with an error.
https://pinpoint-dot-chromeperf.appspot.com/job/14c7ea26240000

All of the attempts failed. See the individual attempts for details on each error.

Comment 12 by dtu@chromium.org, May 31 2018 

Looks like that wasn't the right patch. But even if it was, you'd run into the same issue as https://bugs.chromium.org/p/chromium/issues/detail?id=810022#c23
