Core's tabledrag.js doesn't work with current version

After installing the module (using Drupal 8.8.4) and setting a field to use a draggable table, the rows will not drag and there are javascript errors in tabledrag.js.

It is looking for the first cell of the first row and cannot find it. If you edit the tabledrag.js like this it works:

- 542     if (row.offsetHeight === 0) {
-       rowHeight = parseInt(row.firstChild.offsetHeight, 10) / 2;
-     } else {
-         rowHeight = parseInt(row.offsetHeight, 10) / 2;
-      }
 
+ 542 rowHeight = parseInt(row.offsetHeight, 10) / 2;

OR if you edit the tabledrag.checkbox.js like this, it also works.

- 114      var spacer = '<tr class="tabledrag-sort-spacer"></tr>';
+ 114      var spacer = '<tr class="tabledrag-sort-spacer"><td></td></tr>';
