wp_kses allow checkbox class and checked

Question

I'm having a hard time getting wp_kses to allow the class for an input. These approaches didn't work:

input'    => array( 
  'type'  => true, 
  'class' => true, 
  'name'  => true, 
  'value' => true, 
  'id'    => true 
),

also with array() for class it still is not returned.

Checked is also filtered.

Why do I need this? Well, long story short, the input is in a table which needs to be escaped prior to being printed with echo or with ajax.

According to the codex, you should define your wp_kses list of allowed html elements as below with array() instead of true

$allowed_html = array(
    'input' => array(
        'type'      => array(),
        'name'      => array(),
        'value'     => array(),
        'checked'   => array()
    ),
);
