### Godot version

3.5.1, 4.0 beta 10

### System information

Windows 10

### Issue description

I tried to set a shortcut for `Reparent to New Node`, but the shortcut doesn't trigger. As it's closest neighbour, I tried setting the same shortcut for `Reparent` without problems.

### Steps to reproduce

* Set editor shortcut for `Reparent to New Node` (I set it as Ctrl+G as to group nodes together, but anything is fine - it's not about conflicting shortcut)
* Select a node and press your chosen hotkey

### Minimal reproduction project

N/A (any project is fine, requires modifying editor settings anyway)
ERR_FAIL_INDEX(idx, subresources.size());
				Object *obj = ObjectDB::get_instance(subresources[idx]);
				ERR_FAIL_COND(!obj);
				_push_item(obj);
			}
		}
	}
