Hi, This test is incorrect. I apologize for the false detection.
This issue involves the emergence of precision errors due to a change in the evaluation path for complex number division. Therefore, we will correct the tests. It may take some time due to our internal release process, sorry.
Best regards, Yasuyuki Ohno
