Why console errors disapear when passing the error from a serverAction?

[gcb]

any call to console.error(...) that includes the reference trhow by a call to a server action (as caught by try/catch when using await or .catch(), disappears!

here's a working minimal test case started from the latest version https://github.com/gcb/react_test_case_useActionState/blob/main/app/server-action-client.tsx#L27-L31
(myServerActionDenied() will return a 403, and trigger the catch(err))
