HISTORY: https://results.webkit.org/?suite=layout-tests&test=animations%2Fsuspend-resume-animation-events.html&recent=false&platform=mac&version_name=Ventura&architecture=x86_64 TEXT DIFF: Log start animation move -iteration animation move end animation move DIFF URL: https://build.webkit.org/results/Apple-Ventura-Release-WK1-Tests/266464@main%20(3514)/animations/suspend-resume-animation-events-pretty-diff.html REPRODUCIBILITY: I was able to reproduce this bug on macOS Ventura 13.5 (22G74) ToT on an x86_64 machine using the following command: run-webkit-tests --clobber-old-results --debug --verbose --iterations 100 --child-processes 10 -f --exit-after-n-failures 1 animations/suspend-resume-animation-events.html REGRESSION: I was able to bisect a regression point using the flakiness dashboard. This test reproduced at 256951@main, but it did not reproduce at 256950@main. Changes at 256951@main appear to be directly related to this error, and is likely what caused the failure. 1972670 1 webkit-bug-importer 2023-08-22 11:13:19 -0700 <rdar://problem/114271582> 1972682 2 ben_schwartz 2023-08-22 11:24:35 -0700 Testing on macOS Sonoma indicates this issue persists in versions above macOS Ventura.
