HarmonyOS canvas Path 椭圆无法闭合路径

示例参考如下：

react绘制完成后，执行path2Db.moveTo(xxx,xxx)

如：

// xxx.ets
@Entry
@Component
struct Index {
  private settings: RenderingContextSettings = new RenderingContextSettings(true)
  private context: CanvasRenderingContext2D = new CanvasRenderingContext2D(this.settings)
  private path2Db: Path2D = new Path2D()

  build() {
    Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {
      Canvas(this.context)
        .width('100%')
        .height('100%')
        .backgroundColor('#ffff00')
        .onReady(() =>{
          this.path2Db.rect(20, 20, 100, 100);
          this.context.stroke(this.path2Db)

          this.path2Db.moveTo(200, 200)
          this.path2Db.ellipse(200, 200, 50, 100, 0, Math.PI * 1, Math.PI * 3)
          this.context.stroke(this.path2Db)

          this.path2Db.moveTo(0, 0)
          this.path2Db.rect(0, 0, 50, 50)
          this.context.stroke(this.path2Db)
        })
    }
    .width('100%')
    .height('100%')
  }
}
