Drag and Drop not working

Okay. I'm seeing it's a conflict with the Gin admin theme... 🫠

Gin wraps the main table with a .gin-table-scroll-wrapper element, breaking the following CSS selector:

.field--widget-bert .tabledrag-toggle-weight-wrapper ~ table thead th:first-of-type,
.field--widget-bert .tabledrag-toggle-weight-wrapper ~ table tbody td:first-of-type {
  display: table-cell;
}

In case the maintainer feels like it's worth supporting Gin (for it's a widely adopted admin theme), I've submitted a PR with the updated selector.
