Consider removing dependency on JQuery UI and jQuery UI (and why not core/jquery itself)

+1

I agree it might make sense to remove the dependency on jquery_ui_draggable and replace it by vanilla JS. Perhaps core also provides a dragging functionality in JS or uses a different library?

+1, I also like this proposal.

This shouldn't be too hard using web standards like the draggable HTML attribute and the HTML Drag and Drop API. Specifically the dragstart, drag and dragend events.

We're also interested in this. This is the last contrib project we're using that has the jQuery UI requirements.

jQuery UI Draggable no longer a dependency
