Comment (by desrosj):

 It looks like [51417] contains an anonymous function. While these are
 allowed in some situations, they are not currently allowed for filter and
 action hooks ([https://developer.wordpress.org/coding-standards/wordpress-
 coding-standards/php/#closures-anonymous-functions relevant Core coding
 standard]). Can [51417] be refined to not use a closure?
