ClusterFuzz has detected this testcase as flaky and is unable to reproduce it in the original crash revision. Skipping fixed testing check and marking it as potentially fixed.

I can no longer reproduce this. It's likely that it was the same problem as https://bugs.chromium.org/p/chromium/issues/detail?id=581901.
