Problem/Motivation

On the latest Drupal 11 (haven't bisected the exact version it broke), drag-and-drop in an entity_reference_hierarchy field fails with a JS error Uncaught TypeError: Cannot read properties of undefined (reading 'matches') in tabledrag.js. The only way to nest items is by manually updating the Depth/Order fields.

Steps to reproduce

Install module on latest Drupal 11. Add the field type to an entity. On the entity add/edit form, note that the drag and drop functionality for moving items within the hierarchy is broken.

Proposed resolution

Issue appears to be related to a change of some tabledrag class names in core. Easy fix by updating entity_reference_hierarchy.module. Proposed MR will be added shortly.

Seems it should have been like that since D9, but as I have been using IEF, I had missed it.
I have also made the same changes in the Paragraphs submodule.
