Description:
Animated PNG (APNG) is not supported by all browsers but even on browsers that support it, animation fails when the image is not shown at original size.
Apparently the resizing for the remaining frames fails.
One developer notes that it can be fixed by dissasembling, resizing and assembling the frames
