Description:
fast/images/image-orientation-none-canvas.html

This issue only occurs with iOS wk2 ews and doesn't show up on trunk bots: https://results.webkit.org/?suite=layout-tests&test=fast%2Fimages%2Fimage-orientation-none-canvas.html

The first failure that I see this on the ews queue history was 10/07/20 and failed on clean tree run in https://ews-build.webkit.org/#/builders/24/builds/27591.

Commit r268115 has to do with Refactors TestOptions code in WebKitTestRunne which could have introduced the failures. The change was introduced here https://trac.webkit.org/changeset/268115/webkit.

Reproduced on ews builds:
