Bug 278549 – [ macOS ] 2 tests in TestWebKitAPI.ResourceLoadStatistics are flaky timeouts (failure in EWS)

• Status: NEW
• Component: New Bugs

[Marta Darbinyan]

The following API tests are timing out intermittently both on Ventura and Sonoma. 
TestWebKitAPI.ResourceLoadStatistics.GrandfatherCallback
TestWebKitAPI.ResourceLoadStatistics.MigrateDataFromIncorrectCreateTableSchema

The test became flaky first on Sonoma both on Debug and Release and later on Ventura Release. It's also reproduced in EWS as pre-existing failure.
