If this is incorrect, please let us know why and apply the Test-Predator-Wrong-CLs label. If you aren't the correct owner for this issue, please unassign yourself as soon as possible so it can be re-triaged.

This is not new, but clusterfuzz found it after my CL which enabled pixel dumping by default. If clusterfuzz used --pixel-test option then it could reproduce the issue without my CL. WontFix because it happens in a particularly written layout test only and I'd not put effort on it. It doesn't affect production.
