Similar to https://github.com/dotnet/runtime/issues/105202, likely related to the new tests introduced in https://github.com/dotnet/runtime/pull/104680, affecting only x86 Android emulator at the moment. Do you know if these tests should be disabled or same changes are needed for them to work on x86 Android emulators? @stevejgordon @tarekgh ?

Edit. Looks like the failure is not 100% reproducible since I've seen only two failures on rolling-builds from 2024/07/20 so far.

@matouskozak I'd say it's best and safe to disable these on the affected platforms.

Thank you @stevejgordon, is the same approach the best for https://github.com/dotnet/runtime/issues/105202 as well?
