- **Branch**: main
- **First seen**: 2026-08-24

## Affected Legs
- Android API 36 Pixel 3 XL emulator, CoreCLR, Release

## Error Message
```text
2026-09-02T18:40:58.3979609Z Failed SafeAreaPerEdgeValidation [28 s]
```

## Recommended Action
Investigate per-edge inset application in src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue28986.cs and Issue28986_ContentPage.cs together with the Android safe-area implementation; reproduce on API 36.

Start by reproducing SafeAreaPerEdgeValidation on the Android API 36 Pixel 3 XL emulator in the maui-pr-uitests pipeline. Read src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue28986.cs and Issue28986_ContentPage.cs, then trace the Android safe-area implementation. Done means the test passes reliably across the affected UI-test leg and per-edge insets are applied correctly.
