there is a bug in the CSS :

explicit border:2px solid var(--border); on the input which takes priority over the class :

.demo-uv-input:user-invalid { border-color: var(--red-muted); background: rgba(239,68,68,.04); }

YMMV but when corrected it works for me on latest Edge, Chrome, Firefox (Windows versions)
