Description
Javascript error preventing deletion of taxon from the admin panel. I think this was broken in this commit 2334a76 where dropdown was changed to btn-group

Steps to reproduce
Is currently erroring on the live demo https://v2.demo.sylius.com/admin/taxons/new when attempting to delete a taxon

Possible Solution

Fixed for me when I edited AdminBundle/Resources/assets/controllers/DeleteTaxonController.js and changed

this.modalElement.closest('.dropdown').appendChild(this.modalElement);

to

this.modalElement.closest('.btn-group').appendChild(this.modalElement);
