If you run with `-Xdev`/warnings turned on you get an idea of what's happening:
>>> builtins.__import__('', globals(), locals(), ('foo',), 1)
<stdin>:1: ImportWarning: can't resolve package from __spec__ or __package__,
falling back on __name__ and __path__
<module '__main__' (built-in)>
The check is being done in resolve_name() in import.c
(https://github.com/python/cpython/blob/f9f8e3ce709ceb15c8db8c8dde940daf1febf13d/Python/import.c#L1543).
My guess is there's an off-by-one error in the sanity check logic for
attempting a relative import beyond the top-level package.
