Я делаю прослушиватель кликов для класса '.sticker'. Вызывает функцию editor.insertElement (eventElement). Но эта функция удаляет событие содержимого тега HTML.
На панели стикеров нажмите стикер и в прослушиватель, затем вызовите insertSticker 
функция вызова команды insertSticker 'insertElement (стикер-тег)'
Он попадает в редактор, и его тег img исчезает с панели стикеров.
Как сохранить содержимое тега на панели стикеров после insertElement ()?
Ниже приведен полный код. (Настройка плагина CKEditor 'emoji')
