Js error when saving reference field

The reason is that with the ajax request the form ID changes and the Gin javascript is correctly updating the new form ID for the action buttons and adds a new event listener to them. However, the previous event listener remains in place, and that uses the old form ID.

The solution can be one of these:

• Remove the old event listener before adding the new one
• Let the old ones run as well but prevent the error from happening

Will push an MR in a minute.

OK, please give this MR a try, it should be fixing it.

Thanks! Tested with this as a patch, and the described problem went away. Also tested creating various other field types, editing existing field etc., with no console errors. :)

I confirm that the problem in the node editing form is solved.

Thanks!
