Strange wysiwyg behavior inside group

I’m trying to implement visual editor field inside clonable group like this:

<?php

$meta_boxes[] = [
    'title'           => 'Текстовые триггеры',
    'id'              => 'text-trigger',
    //'description'     => 'A custom hero content block',
    'type'            => 'block',
    'icon'            => 'awards',
    'category'        => 'tsm',
    'context'         => 'side',
    'render_template' => get_template_directory() . '/gutenberg/text-trigger.php',
    'fields'          => [
        [
            'id'                => 'triggers',
            'type'              => 'group',
            'name'              => 'Контент',
            'clone'             => true,
            'sort_clone'        => true,
            'add_button'        => '+',
            'collapsible'       => true,
            'group_title'       => 'Элемент {#}',
            'save_state'        => true,
            'fields'            => [
                [
                    'id'                => 'icon',
                    'type'              => 'single_image',
                    'name'              => 'Иконка',
                ],
                [
                    'id'                => 'text',
                    'type'            => 'wysiwyg',
                    'name'                => 'Текст',
                    'options'             => [
                            'media_buttons'   => false,
                            'teeny'           => true,
                            'textarea_rows'       => 10,
                    ],
                ],
            ]
        ],
    ],
];

And that’s what i get (different bugs on load, sorting and adding new):
