[PureWeen]

Build Information

Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1349891
Leg Name: MacCatalyst UITests CoreCLR / Controls Image,ImageButton,IndicatorView,InputTransparent,IsEnabled,IsVisible

Error Message

{
  "ErrorMessage": "Snapshot different than baseline: Issue16918Test.png",
  "BuildRetry": false,
  "ExcludeConsoleLog": false
}

Description

Issue16918Test fails with a screenshot baseline mismatch on MacCatalyst in every net11.0 CI build checked (5/5 builds). This is unrelated to the BottomNavigationView MaxItemCount issue (#34586) — it's a standalone flaky Mac test.

Previously tracked as part of #34586 but split out since it has a different root cause.

Pattern validated with Test-KnownIssuePattern.ps1: PASS
