WordPress' code just... wasn't. This is now dealt with. Props jrf, pento, netweb, GaryJ, jdgrimes, westonruter, Greg Sherwood from PHPCS, and everyone who's ever contributed to WPCS and PHPCS. Fixes #41057. Built from https://develop.svn.wordpress.org/trunk@42343 git-svn-id: http://core.svn.wordpress.org/trunk@42172 1a063a9b-81f0-0310-95a4-ce76da25c4cd
