Relation widget shows "No {{fields.name}}" when collapsed and search results always return "No options"

**Describe the bug**

Relation widget shows "No {{fields.name}}" when collapsed and search results always return "No options".

**To Reproduce**

1. Go to a relation widget.
2. See collapsed state shows "No {{fields.name}}".
3. Expand relation widget.
4. See value _does_ exist in the selected dropdown value.
5. Focus into search and attempt to search for an entry
6. See that all searches return "No options".

**Expected behavior**

Collapsed state of relation widget should show the selected entry. Relation widget should also return results when searching within the field (when there are matching results).

This was not an issue when my client last made an update on 7/6/2025. Could this be related to #7497 ?
