LockTimeOut not working?

[wfvdijk]

I am running the integritycheck with 'CHECKTABLE' , @tablock = 'Y', a @lockTimeout of 5 and a @LockMessageSeverity of 10. However, when running and hitting a table which is being used I get error 5245 (which is almost the same as error 1222). Since this error is not handled in the stored procedure, it's always returning severity 16 resulting in a failed operation. Am I doing something wrong, or should I classify this as a bug? (using SQL 2022)
