Missing required asterisk in Claro

Problem/Motivation

When using a Draggable Table field widget on a required field, the table header markup for a tabledrag table differs from a the markup seen in Claro and Classy, resulting in a missing required asterisk.

Compare this markup for a required multi-value Autocomplete widget field in Claro where the required asterisk appears as expected:

To the markup for a required Draggable Table field in Claro where the required asterisk does not appear:

Both use this template:
docroot/themes/contrib/classy/templates/dataset/table.html.twig

In all of Claro's CSS the only styling for required asterisks is this:

.form-item__label.form-required::after,
.fieldset__label.form-required::after {
  display: inline-block;
  margin-inline: 0.15em;
  content: "*";
  color: var(--color-maximumred);
  font-size: 0.875rem;
}

Which means that unless the Draggable Table thead th contains an element with the classes .form-item__label.form-required, it will be missing the required asterisk.
