2026-08-16T16:59:48.9141950Z Snapshot different than baseline: VerifyLabelWithTextAndLineBreakModeCharacterWrap.png (2.68% difference)
```

## Recommended Action
Compare the MacCatalyst actual and baseline images for `src/Controls/tests/TestCases.Shared.Tests/Tests/FeatureMatrix/LabelFeatureTests.cs`; determine whether CharacterWrap measurement regressed or the baseline intentionally changed.

Start with src/Controls/tests/TestCases.Shared.Tests/Tests/FeatureMatrix/LabelFeatureTests.cs and the maui-pr-uitests build linked in the issue. Compare the MacCatalyst actual and baseline images for VerifyLabelWithTextAndLineBreakModeCharacterWrap, then determine whether CharacterWrap measurement regressed or the baseline intentionally changed. Done means the visual test and baseline agree for the intended behavior.
