 This function:

 {{{#!php
 function wp_kses_post( $data ) {
         return wp_kses( $data, 'post' );
 }

 }}}
 https://github.com/WordPress/wordpress-
 develop/blob/169f2a432dcb000ccee0d14c50b76a62218115b3/src/wp-
 includes/kses.php#L1575

 Doesn't work because the second parameter is a string but wp_kses()
 expects an array.

 {{{#!php
  * @param string $string            Content to filter through kses
  * @param array  $allowed_html      List of allowed HTML elements
  * @param array  $allowed_protocols Optional. Allowed protocol in links.
  * @return string Filtered content with only allowed HTML elements
  */
 function wp_kses( $string, $allowed_html, $allowed_protocols = array() ) {
 }}}

 We get:
