Form items not displayed inside table when using table fieldgroup in node edit form

Problem/Motivation

I have a Drupal 7 site with a content type that has several fields for a specifications table, and I use this module to output the table both in the node edit and node view modes. This works perfectly in Drupal 7.

I am now upgrading this site to Drupal 10, and after installing this module, I noticed that the above described table displays properly in the node view mode, but not in the node edit view.

Peeking into the source, it seems as if the table is empty, and the form items are displayed outside the table markup.

Steps to reproduce

1. Create content type with several fields.
2. In the form display, add a Table fieldgroup.
3. Move the fields inside the Table fieldgroup and save.
4. Create a new node of the content type, and in the node create page you can see that the form items are not in table format.
