Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/chromium/src/+/4ea14eb904e6d48aab3b9d635176e49c5fd68f3e ([run_web_tests] Remove --pixel-test/--pixel-tests option).

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.
Status: WontFix (was: Assigned)
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.
