This is a micro-optimization to avoid an unnecessary `is_string()` check. Follow-up to [23555], [48433]. Props dilipbheda, audrasjb, staurand, rollybueno, psykro, westonruter, SergeyBiryukov. Fixes #63211. git-svn-id: https://develop.svn.wordpress.org/trunk@61103 602fd350-edb4-49c9-b593-d223f7449a82
