In a future commit, ownership of animation will be transferred from these clients to `AnimatedDecodedImageData` and we will need a way to invalidate them for new frames. This also revealed some `ImageProvider`s which don't yet support animated images (e.g. `<input type="file">`, `<object>`, etc) but that is left as a FIXME for now.
