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.

Marking as WontFix, since it no longer repros on original revision, and we're not seeing this happen anymore. (I'm also not the right owner).
