Description

## Summary
`GlideStaticEqualsGlideGet` repeatedly fails with `NullReferenceException` in Android device tests.

## Build Information
- **Pipeline**: maui-pr-devicetests
- **Build**: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1584588
- **Build ID**: 1584588
- **Branch**: net11.0
- **First seen**: 2026-09-05
- **Occurrences**: 2 in last 10 builds

## Affected Legs
- DeviceTestsAndroid_CoreCLR / Android
- DeviceTestsAndroid_Mono / Android

## Error Message
```text
09-05 22:36:29.674 2922 10761 I DOTNET : 2) [FAIL] GlideStaticEqualsGlideGet Test name: GlideStaticEqualsGlideGet
09-05 22:42:30.436 24942 7818 I DOTNET : 1) [FAIL] GlideStaticEqualsGlideGet Test name: GlideStaticEqualsGlideGet
System.NullReferenceException: Object reference not set to an instance of an object.
```

## Investigation Context
The same test fails in both CoreCLR and Mono Android work items in build 1584588. A preceding completed build contains the same named failure, establishing recurrence across two builds.

Research direction

Start with the GlideStaticEqualsGlideGet test in the maui-pr-devicetests pipeline and reproduce build 1584588 on the DeviceTestsAndroid_CoreCLR and DeviceTestsAndroid_Mono legs. Trace the reported NullReferenceException; done means the test passes on both Android work items without the recurring failure.
