AnimatedVectorDrawable in placeholder or error state is not working, even call start() before state change

DisplayRequest builder like this

  val placeholderDrawable = ContextCompat.getDrawable(this@with,R.drawable.animated_placeholder)
                                                as AnimatedVectorDrawable
  val errorDrawable = ContextCompat.getDrawable(this@with,R.drawable.animated_error)
                                                as AnimatedVectorDrawable

  this.placeholder(placeholderDrawable)
                                            .error(errorDrawable)
                                            .transformations(BlurTransformation())
                                            .crossfade()

adding a state listener

 this.listener(onCancel = {
     println("result.drawable::Cancel")
 }, onError = {_,error->
     println("result.drawable::Error ${error.drawable}")
     (error.drawable as SketchStateAnimatableDrawable).autoPlay()
       placeholderDrawable.reset()
       errorDrawable.autoPlay()
 }, onStart = {
     println("result.drawable::Start :")
       placeholderDrawable.autoPlay()
 }, onSuccess = {_,result->
     println("result.drawable::Success :${result.drawable}")
       .autoPlay()
 })

是否开启了 resizeApplyToDrawable()，目前这个功能有些 bug

现在最新的 3.2.1-beta03 版本在 ImageVie 上应该可以无障碍的播放 AnimatedVectorDrawable 了，

但在 compose 上，已知 api29 以上依然无法播放，测试代码如下：

val context = LocalContext.current
val painter = remember {
      val drawable = ContextCompat.getDrawable(context, R.drawable.animated_placeholder) as AnimatedVectorDrawable
    DrawablePainter(drawable!!)
}
Image(
    painter = painter,
    contentDescription = "",
    contentScale = ContentScale.Crop,
    modifier = Modifier.fillMaxSize()
)

这段代码没有涉及到 sketch，所以这个 bug 只能等 compose 团队去解决
