When using the "Add another" popup for a ***ForeignKey field*** in the
Django admin and the same ModelAdmin has a ManyToManyField with
***filter_horizontal***, the popup window does not close properly after
adding the related object.
Instead, the popup remains open and white (blank), and the browser console
throws the following error:
{{{
:8000/static/admin/js/SelectBox.js:60 Uncaught TypeError: Cannot read
properties of undefined (reading 'push')

}}}
This seems to be caused by this block in RelatedObjectLookups.js:
{{{
// Update SelectBox cache for related fields.
if (typeof SelectBox !== "undefined" && SelectBox.cache[currentSelect.id])
{
SelectBox.add_to_cache(select.id, option);
SelectBox.redisplay(select.id);
}
}}}
=== Steps to Reproduce
1. Register a ModelAdmin with:
* A ForeignKey field (with an "Add another" popup)
* A ManyToManyField using filter_horizontal
2. Click the "Add another" button next to the ForeignKey field
3. In the popup, add the new object and submit
4. The popup window stays open with a white screen
5. Console shows a JavaScript error from SelectBox.js
=== Expected Behavior
The popup should close normally and update the original select field with
the new object, as it does when filter_horizontal is not present.
=== Workaround
Commenting out or removing the SelectBox.add_to_cache and
SelectBox.redisplay lines in RelatedObjectLookups.js avoids the error and
restores expected behavior.
=== Version
* Django 5.2.X
* Reproducible in the default admin interface
