In the Web Player code generator (https://lottiefiles.com/web-player) if you check Play Mode as Bounce, it adds mode="bounce" to the HTML. However, mode="bounce" doesn't work when I tried it outside of that page, but playMode="bounce" does (see https://codepen.io/tcmulder/pen/YzgwWdz). Should that generator be updated to use playMode="bounce", or maybe document how to get mode="bounce" to bounce since it doesn't when simply copied/pasted.
