Comment:

 This is still a problem, and it crashes WordPress with a fatal error.

 https://wordpress.stackexchange.com/questions/408101/broken-kses-php-
 function-wp-kses-named-entities-crashes-wordpress/408137#408137

 As you can see from the stack trace -- and I checked all plugins and
 themes with grep -- no plugin or theme is setting $allowedentitynames

 How is it getting set to null? No idea.

 Anyway, the solution is pretty simple:

 wp-includes/kses.php line 1866

 {{{
 if ( empty( $matches[1] ) OR empty( $allowedentitynames ) ) {
 }}}
