Blink has good support for animated images but UI code in Chrome is limited. We can workaround some of these limitations by using WebUI and avoiding decode on the browser process side.
APNG decode support in the browser would not just be useful for animated images in browser UI code but also allow us to improve URL handlers used by WebUI. E.g. chrome://theme can returned scaled animated images.
