Deprecated since version 1.9: In older versions, you could add an allow_tags attribute to the method to prevent auto-escaping. This attribute is deprecated as it’s safer to use format_html(), format_html_join(), or mark_safe() instead.
2.0 release notes: Support for the allow_tags attribute on ModelAdmin methods is removed.
Возможно, оно?
В исходниках django-admin-sortable2 allow_tags используется, видимо надобно писать им багрепорт
