            Bug ID: 251219
           Summary: [ macOS ] fast/images/animated-avif.html is broken

           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified

          Severity: Normal

fast/images/animated-avif.html

is broken in multiple ways on macOS. 


For Ventura WK2 it is a constant timeout, and a flaky crash, but the flaky crash is being investigated on another bug. 

For Ventura WK1 it is a constant Imagefailure.

It is a constant ImageOnlyFailure on Monterey WK2, but only on systems running on Apple Silicon, so I wonder if we just need to adjust the pixel tolerances on that platform for apple silicon in order to fix that?
