`$this` is a pseudo-variable that cannot be used as the name of a function parameter, so renaming these helps prevent errors when implementing hook callback functions. Fixes #53457 Built from https://develop.svn.wordpress.org/trunk@51518 git-svn-id: http://core.svn.wordpress.org/trunk@51129 1a063a9b-81f0-0310-95a4-ce76da25c4cd
