33989	"filter_horizontal/filter_vertical giving ""This field is required"" error even when objects are selected."	Harshiv Pandya	nobody	"Django Admin after updating to Django 4.1 causes **This field is required.** error message when saving object after adding any ManyToManyField relation by using filter_horizontal and filter_vertical options. Problem does not persist when I do not use the horizontal and vertical filters and during addition of objects through Django shell. Happens only via the admin page. I downgraded the Django to 4.0.6 and tried replicating, it works fine there. 

Looks like if I tried to save object on Django 4.1 without reloading CSS from 4.0.6, it still worked."	Bug	closed	contrib.admin	4.1	Normal	duplicate	django-admin, filter-horizontal, filter-vertical	Harshiv Pandya	Unreviewed	0	0	0	0	0	0
