re-baseline committed at https://trac.webkit.org/changeset/280617/webkit
Comment 3 Alexey Proskuryakov 2021-08-06 10:50:59 PDT
Is this really done? A flaky failure cannot possibly be fixed by updating -expected.txt.
Comment 4 Eric Hutchison 2021-08-06 12:21:04 PDT
Upon review, failure is consistent. Issue not resolved by re-baseline.
Comment 5 Eric Hutchison 2021-08-06 12:59:40 PDT
Performed re-baseline process after updating with incorrect file. Will verify resolution before closing.
