PLE0307 triggers on __str__ that always raises an exception

[ThiefMaster]

class PasswordHash:
    def __str__(self):
        raise RuntimeError('This hash cannot be used in a string context')

$ ruff check --isolated --select PLE0307 --preview --no-cache --output-format concise rufftest/ruff_sample.py
rufftest/ruff_sample.py:2:9: PLE0307 `__str__` does not return `str`

It works as expected when raising NotImplementedError, but IMHO any raise-only body should avoid triggering this.
