I couldn't figure out the best area label to add to this issue. Please help me learn by adding exactly one area label.

[jkotas]

The test depends on internal implementation details that got changed by #34813

Tagging @vitek-karas, @swaroop-sridhar as an area owner. If you would like to be tagged for a label, please notify danmosemsft.

@EgorBo Could you please take a look? This test is failing in all CoreCLR jobs.

[jaredpar]

How was #34813 green given that it broke CI after merge? Did it conflict with a different green PR post merge?

[jkotas]

It did not run CoreCLR tests. I do not understand why.

The CoreCLR tests should run for any changes under src/libraries/System.Private.CoreLib : https://github.com/dotnet/runtime/blob/master/eng/pipelines/coreclr/ci.yml#L9
