Start with System.Net.Security.Tests.CertificateValidationRemoteServer.ConnectWithRevocation_WithCallback and the failure at CertificateValidationRemoteServer.cs:370. Run the named test and inspect the SslStream stack location in SslStream.Protocol.cs:1306, along with pull request #132933. Done means the test reliably observes the expected Revoked status instead of RevocationStatusUnknown.
