Marking look again as the test had a previous change in behavior that this regression could fall under, and there are no commits in the range that would obviously cause this: dotnet/runtime@96ae7cf...aaafed2.

[LoopedBard3]

Restabilized at previous value likely due to dotnet/runtime#110277. (Dec 3rd 2024)
