Relation widget does not change when referenced item is deleted #5750
Description
Context:
I currently have a site where the products are managed in a folder collection (will refer to this as the "Catalog"), this is where the base data for a product is stored. I also have a file collection that includes a file for managing the order in which the products are displayed (will refer to this as the "Display Order"). In the "Display Order", I have a list widget where the list items are relation widgets.
Bug:
When a product is removed from the "Catalog" any relation widgets referencing that deleted product in the "Display Order" are not updated.
Expected Behavior:
There should be some kind of error or behavior for when an item referenced by a relation widget is removed.
