Unable to reproduce and has no security implications. I'd argue we should close as WontFix but over to skia in case they feel differently.

Status: WontFix (was: Untriaged)
ClusterFuzz testcase 5501087242256384 is flaky and no longer crashes, so closing issue.

If this is incorrect, please add ClusterFuzz-Wrong label and re-open the issue.
