370 Regression: Modals do not close #12335
Description
Apply #12321 or test in back-end using the xtd editors when editing an article: Insert article, insert menu, insert pagebreak.
The modals should close after selecting or Inserting.
They don't.
JS error: ReferenceError: jModalClose is not defined
It is specially weird for Pagebreak where it displays the site page in the modal after inserting
