“Search Exclude” meta box disappeared after last update

On my site, instead of the “Classic Editor” plugin, I use the function in the theme’s functions.php file

add_filter('use_block_editor_for_post', '__return_false', 10);
add_filter('use_widgets_block_editor', '__return_false');

You probably didn’t consider that someone could restore the classic editor this way.
I suspect that you’ve added some function that detects the existence of the “use_block_editor_for_post” and “use_widgets_block_editor” functions and then doesn’t display the “Search Exclude” meta box. I’d appreciate it if you could fix it.
