lukasza@ -- can you please take a look at this and help triage?

inferno@, mbarbella@, tanin@: The bug reports the regress range as: https://cluster-fuzz.appspot.com/revisions?job=windows_syzyasan_content_shell&range=414958:414959
That's just a SKIA roll which only changes the version number.

ClusterFuzz testcase is flaky and no longer reproduces, so closing issue.

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