28866	InlineAdminFormSet should include InlineModelAdmin's Media before its formset's Media	clincher	nobody	"I was trying to use django-map-widgets with django2.0rc1 and it didn't show the widget. The problem is that widget js-files were included before django-admin jquery's files which it relies on.
I went deeper and found that Media.merge method are pretty much implicit which breaks Python zen guidelines. The implicity caused by MediaOrderConflictWarning check, without that check code might be way more simplier. More than that, the realization of that check is not working. I got few ideas how to solve it, but honestly I would prefer just remove it and make the method really simple.

Example of lists with which the method doesn't work properly:
list_1 = ['admin/js/vendor/jquery/jquery.js', 'admin/js/jquery.init.js', 'admin/js/core.js', 'admin/js/admin/RelatedObjectLookups.js', 'admin/js/actions.js', 'admin/js/urlify.js', 'admin/js/prepopulate.js', 'admin/js/vendor/xregexp/xregexp.js']
list_2 = ['https://maps.googleapis.com/maps/api/js?libraries=places&key=', 'mapwidgets/js/jquery_class.js', 'mapwidgets/js/django_mw_base.js', 'mapwidgets/js/mw_google_point_field.js', 'admin/js/vendor/jquery/jquery.js', 'admin/js/jquery.init.js', 'admin/js/inlines.js']

I can easily make a patch without the warning check. Also can check the order, but it's gonna be very different way from what's there now.

I set serverity to blocker since it's totally breaks possibility to use Django with many other libraries"	Bug	closed	contrib.admin	2.0	Release blocker	fixed	formset, media, admin	Johannes Maron	Ready for checkin	1	0	0	0	0	0
