title: WooCommerce hide order item meta from front end (not admin)
body: <p>I have a couple of order item meta details that I would not like the customer to see (on the view orders page under account info). I have found a filter that will remove this data from the ADMIN (where I would still like to see it), but can't find a similar filter to remove it from the FRONT END (where it should be hidden). </p>
  
  <p>Here is the code that will (uselessly, for me) remove it from the back end admin:</p>
  
  <pre><code>add_filter( 'woocommerce_hidden_order_itemmeta', 'add_hidden_order_items' );
  function add_hidden_order_items( $order_items ) {
      $order_items[] = 'paid_already';
      $order_items[] = 'variation_sku';
      // and so on...
      return $order_items;
  }
  </code></pre>
