valid formset with invalid deleted form raises AttributeError when trying to access cleaned_data

[valtron2000@…]

Example (run in manage.py shell):

from django.forms import Form, BooleanField
from django.forms.formsets import formset_factory

class F(Form):
	a = BooleanField()

FS = formset_factory(form = F, can_delete = True)

fs = FS(data = {
	'form-MAX_NUM_FORMS': '',
	'form-INITIAL_FORMS': '1',
	'form-TOTAL_FORMS': '1',
	'form-0-a': '',
	'form-0-DELETE': 'on',
})

assert fs.is_valid()

# fs.forms[0].cleaned_data raises AttributeError
print fs.cleaned_data

This can be fixed by changing BaseFormSet._get_cleaned_data to only return the cleaned_data of non-deleted forms:

def _get_cleaned_data(self):
    """
    Returns a list of form.cleaned_data dicts for every form in self.forms.
    """
    if not self.is_valid():
        raise AttributeError("'%s' object has no attribute 'cleaned_data'" % self.__class__.__name__)
    return [form.cleaned_data for form in self.forms if not self._should_delete_form(form)]

This should have been fixed recently (see #5524, ​https://github.com/django/django/commit/121fd109de09ece4e263e508f9034df9b583da46). cleaned_data is now always available once a form has been validated. Reopen if I missed the point.
