Description Truitt Savell 2021-07-26 17:08:25 PDT

It looks like the changes in https://trac.webkit.org/changeset/279855/webkit

broke TestWebKitAPI.AppleLanguagesTest.UpdateAppleLanguages on Big Sur

history:
https://results.webkit.org/?suite=api-tests&test=TestWebKitAPI.AppleLanguagesTest.UpdateAppleLanguages

Diff:
TestWebKitAPI.AppleLanguagesTest.UpdateAppleLanguages
        
        /Volumes/Data/worker/bigsur-release/build/Tools/TestWebKitAPI/Tests/WebKit/OverrideAppleLanguagesPreference.mm:179
        Value of: didChangeLanguage
          Actual: false
        Expected: true
        
        
        /Volumes/Data/worker/bigsur-release/build/Tools/TestWebKitAPI/Tests/WebKit/OverrideAppleLanguagesPreference.mm:180
        Value of: preferenceObserverPreferenceDidChangeCalled
          Actual: false
        Expected: true
        
        
        /Volumes/Data/worker/bigsur-release/build/Tools/TestWebKitAPI/Tests/WebKit/OverrideAppleLanguagesPreference.mm:181
        Expected equality of these values:
          @"en-US"
            Which is: "en-US"
          preferredLanguage()
            Which is: "en-GB"

I am able to reproduce this with command:
run-api-tests TestWebKitAPI.AppleLanguagesTest.UpdateAppleLanguages

I bisected this and was able to reproduce it on r279855 but no r279854
