Comment (by SergeyBiryukov):

 As noted in comment:10, this was previously attempted in [30640] and
 reverted in [32171] as a security fix for
 [https://wordpress.org/news/2015/04/wordpress-4-1-2/ WordPress 4.1.2]. It
 would be great to confirm with the Security Team that [52829] does not
 reintroduce any issues.
