It seems like django.core.mail.EmailMultiAlternatives does not include the
body or the alternative if the body is falsey and if it has attachments.
{{{
>>> from django.core.mail import EmailMultiAlternatives
>>> m = EmailMultiAlternatives(body="")
>>> m.attach_alternative("<img
src='https://example.com/example_image.png'>", "text/html")
>>> "example_image.png" in m.message().as_string()
True
>>> m.attach('example.txt', "example attachment", 'text/plain')
>>> "example_image.png" in m.message().as_string()
False
>>> print(m.message().as_string())

It is probably because of
[https://github.com/django/django/blob/53ccffdb8c8e47a4d4304df453d8c79a9be295ab/django/core/mail/message.py#L351
this] conditional. It checks if body is truthy, even though it is
sometimes called from EmailMultiAlternatives with a msg that should be
included.
