When --import is used, the ESM loader is used to handle even pure CJS entry points, and it can run into CJS module facades in the evaluating state when the parent CJS module is being evaluated. In this case it should be allowed, since the ESM <-> CJS cycles that are meant to be disallowed (for the time being) should already be detected before evaluation and wouldn't get here, and CJS <-> CJS cycles are fine.
