/**
 * @fileoverview For ContentTask.spawn, this will automatically declare the
 *               frame script variables in the global scope.
 *               Note: due to the way ESLint works, it appears it is only
 *               easy to declare these variables on a file-global scope, rather
 *               than function global.
