HarmonyOS 使用drawing.canvas绘制本地Image时，提示参数错误

使用drawing.canvas绘制本地Image时，执行到canvas.drawImage(this.pixelMap, 0, 0);时报出参数错误问题

async draw(context : DrawContext) {
  const canvas = context.canvas;
  // 获取resourceManager资源管理
  const resourceMgr : resourceManager.ResourceManager = this.comContext.resourceManager;
  await resourceMgr.getRawFd('ic_in_selected_red.png').then(async (rawFileDescriptor : resourceManager.RawFileDescriptor) => {
    console.log("Succeeded in getting RawFd")
    const imageSource : image.ImageSource = image.createImageSource(rawFileDescriptor)
    await imageSource.createPixelMap().then((pixelMap: image.PixelMap) => {
      this.pixelMap = pixelMap
      console.log("Succeeded in creating PixelMap")
    }).catch((err : BusinessError) => {
      console.error("Failed to creating PixelMap")
    });
  }).catch((err : BusinessError) => {
    console.error("Failed to get RawFd")
  });

  console.error("draw image")
  try {
    if (this.pixelMap != null) {
      canvas.drawImage(this.pixelMap, 0, 0);
    }
  } catch (e) {
    console.error("draw image error=" + e)
  }
}

这个时序影响着参数调用？我现在通过await控制时序了，最后调用canvas.drawImage(this.pixelMap, 0, 0)，也是返回Error: Invalid params.

可以基于上面的代码调试（ps 正常业务内我们加载一张图片不会放在aboutToAppear中)

问题描述：异步绘制时，在drawImage调用前，arkui就已经调用了drawing的canvas的ResetCanvas接口，导致对应的canvas被释放了而无法绘制drawImage。
