Перестала работать кастомизация таблиц в области

[FlashWS]

Данный коммит https://github.com/LaravelRUS/SleepingOwlAdmin/commit/d1a9000510628e5f80a5c11a5bfcea551541db58 отвалил функционал расширения таблиц (https://sleepingowl.ru/docs/displays#extend), теперь кастомный класс невозможно отобразить в области before.panel
