Thanks KyleMac for the report, André Cruz for the initial patch and
Hiroki Kiyohara for the tests.

The regression was caused by patch to ticket #15316 and was fixed by a
patch to #10790.

It's useful to be able to list all the (flattened) keys of a
ContextList, to help you figure out why the variable that's supposed
to be there is not.

No .values() or .items() added as the definition for those aren't clear.

The patch is Chris Wilson's patch from pull request 1065 with some
modifications by committer.

Fixed #18681 -- BaseModelAdmin.get_form and InlineModelAdmin.get_formset no longer bypass get_fieldsets

Thanks weipin for the report and Baptiste Mispelon for the patch.

Correctly calculate the ``aggregate_start`` offset from loaded fields,
if any are deferred, instead of ``self.query.select`` which includes all
fields on the model.

Also made some PEP 8 fixes.

Chicago was missing.

normalize_email should be called on the instance, not the class. This
has the same effect normally but is more helpful to subclassers. When
methods are called directly on the class, subclasses can't override
them.

Refs #15653.

Thanks Edwin.

The cause was assuming that an unordered queryset returns the values
always in the same order.
