Pop-up closing... freezes on admin interface

[jonfroehlich]

This has been happening for a long time. When you try to add an author in a pub page, the pop-up modal does not auto-close

In /static/admin/js/SelectBox.js:56

Uncaught TypeError: Cannot read properties of undefined (reading 'push')
    at Object.add_to_cache (/static/admin/js/SelectBox.js:56)
    at dismissAddRelatedObjectPopup (/static/admin/js/admin/RelatedObjectLookups.js:74)
    at popup_response.js:13

I think this is now fixed... I'm not seeing it anymore at least.

Narrator: this was not fixed.

We do have a solution, however... which I will check in shortly.

This is now fixed with our custom sortedm2m_filter_horizontal_widget.
