document-compat-mode-detectable document.compatMode reports CSS1Compat (standards) or BackCompat (quirks); the change targets BackCompat documents. script
named-anchor-lookup-via-getelementsbyname getElementsByName is case-sensitive in all modes — used as a parallel surface that already matched what fragment navigation now does. script
