At the beginning of this project, and it was back in 2013, jQueryUI Dialog was used for various actions inside Administration panel.
It should be replaced with the native HTML dialog now, and the old code that was using jQuery should be cleaned up. This should also lead to a lesser dependency from jQuery, in order to completely remove it, in the future, and use only vanilla JS.
