Per the documentation standards, the `@global` tag is meant to list PHP globals used within functions or methods. The code in question uses the variable in global namespace, but does not explicitly declare it. Props jayupadhyay01, dswebsme. Fixes #46602. Built from https://develop.svn.wordpress.org/trunk@45233 git-svn-id: http://core.svn.wordpress.org/trunk@45042 1a063a9b-81f0-0310-95a4-ce76da25c4cd
