[ghost]

Submited widgets after refresh page, drops in unactive section.
Auto add_theme_support('widgets') don't works in register_sidebar(array)

So problem, when i add register_sidebar with function, widgets don't show in adminbar

<?php
add_action('widgets_init', 'ju_widgets');

//from includes/widgets.php
function ju_widgets()
{
	register_sidebar([
		'name'						=>	__('Sidebar Primary', 'udemy'),
		'id'							=>	'ju_sidebar',
		'description'			=>	__('Sidebar for the theme Udemy', 'udemy'),
		'before_widget'		=>	'<div id="%1$s" class="widget clearfix %2$s">',
		'after_widget'		=>	'</div>',
		'before_title'		=>	'<h4>',
		'after_title'			=>	'</h4>'
	]);
}
?>

but when i add theme support widgets in functions.php

<?php
add_theme_support('widgets');
?>

It shows in admin bar, when i go in widgets page see block editor add widgets into Sidebar Primary submit updates. After submit changes i refresh the widgets page (current page) all my components (widgets) drops in unactive section.

I build my functions.php from few php files, i think it helps.

functions.php
|
includes/widgets.php

In php.ini i change only uploads_max_size from 2M to 50M, max_execution_time from 30 to 500, post_max_size from 2M to 50M

Add Comment, it correctly work only if i write in one file functions php. So functions.php before - get bug

<?php

// Setup
define('JU_DEV_MODE', true);

// Includes
include('includes/front/enqueue.php');
include('includes/setup.php');
include('includes/custom-nav-walker.php');
include('includes/widgets.php');

// Supports
/* add_theme_support('widgets');
add_theme_support('widgets-block-editor'); */

// Hooks
add_action('wp_enqueue_scripts', 'ju_enqueue');
add_action('after_setup_theme', 'ju_setup_theme');
add_action('widgets_init', 'ju_widgets');

// Shortcodes

And variant without bug, i add inital function code in functions.php - it solve problem but code with includes don't work correctly php7.4 (wordpress: latest)

<?php

// Setup
define('JU_DEV_MODE', true);

// Includes
include('includes/front/enqueue.php');
include('includes/setup.php');
include('includes/custom-nav-walker.php');
//include('includes/widgets.php');

// Supports
add_theme_support('widgets');
add_theme_support('widgets-block-editor');

function ju_widgets()
{
	register_sidebar([
		'name'						=>	__('Sidebar Primary', 'udemy'),
		'id'							=>	'ju_sidebar',
		'description'			=>	__('Sidebar for the theme Udemy', 'udemy'),
		'before_widget'		=>	'<div id="%1$s" class="widget clearfix %2$s">',
		'after_widget'		=>	'</div>',
		'before_title'		=>	'<h4>',
		'after_title'			=>	'</h4>'
	]);
}

// Hooks
add_action('wp_enqueue_scripts', 'ju_enqueue');
add_action('after_setup_theme', 'ju_setup_theme');
add_action('widgets_init', 'ju_widgets');

// Shortcodes
