Description

This is not exactly a bug and not a feature request however it's not explained in the documentation and took me a tad to figure it out.

Meta fields are not displayed if you are using the classic editor instead of Gutenberg. This would be great if its possible to use them with the classic editor.

Steps to reproduce

add the following to App\Hooks\Application.php

Filter::add('use_block_editor_for_post', '__return_false', 10);

Add your meta fields

Metabox::make('properties', 'post')
    ->add(Field::text('author'))
    ->add(Field::text('isbn'))
     ->add(Field::integer('publication_year'))
     ->set();

Whats displayed is the meta box properties without the fields.

Expected behavior

Display the fields.
