According to https://html.spec.whatwg.org/multipage/obsolete.html#non-conforming-features <rb>, <big>, <tt> are obsolete, non-conforming. But I get errors only for <big> and <tt>, not for <rb>. Example: <!DOCTYPE html> <html lang=''> <title>rb</title> <p><big>BIG</big> <tt>TT</tt> <ruby><rb>RB<rt>RT</ruby></html>Received on Saturday, 1 October 2022 09:29:59 UTC
