What is expected?

根据文档中的指导，把挂载位置和函数调用结合，并不能使Drawer挂载到相应的位置，会挂载到body上。但是，一样的配置，不使用函数调用，直接用a-drawer的方式，却可以挂载到想要去的地方。（配置、挂载点均一致，唯一的区别只是component方式还是api方式）

Steps to reproduce

// 用这种方式能挂载
<a-drawer
  popup-container="#parentNode"
  :visible="visible"
  @ok="handleOk"
  @cancel="handleCancel"
>
  <template #title> Title </template>
  <div>
    You can customize modal body text by the current situation. This modal
    will be closed immediately once you press the OK button.
  </div>
</a-drawer>

//函数方式不行
Drawer.open({
    title: "Info Title",
    content: "This is an info message",
    width: 340,
    popupContainer: "#parentNode",
  });
