bug with tinymce

Hi! In my admin panel I don’t use Visual editor in wysiwyg (disabled it in my user settings). I always use Plain Text by default.

For Metabox I use this code:

             array(
                    'id' => $prefix . 'docs',
                    'type' => 'group',
                    'clone' => true,
                    'sort_clone' => true,
                    'add_button' => esc_html__( 'add', $mx ),
                    'fields' => array(
                        array(
                            'id' => 'h2',
                            'type' => 'text',
                            'name' => esc_html__( '', $mx ),
                            'placeholder' => esc_html__( 'header', $mx ),
                        ),
                        array(
                            'id' => 'text',
                            'type' => 'wysiwyg',
                            'name' => esc_html__( '', $mx ),
                            'raw' => true,
                            'options' => array( 'textarea_rows' => 10, ),
                        ),
                    ),
                ),

As you can see, this code allow me to clone field with wysiwyg type. BUT! When when I add a new field by click to “add” button, Metabox is switching to tinymce although it even not exists!

This is console screenshot: https://i.ibb.co/R9kNHt5/Screen-Shot-2020-04-18-at-13-26-51.png

Same stuff happens when I just moving field with wysiwyg type (‘sort_clone’ => true).

Hope you can understand me.
