Describe the bug

以下测试代码中，如果在 textarea 中修改字符串，input的文本会变化，但宽度没有跟着变。
当在input中修改字符串时，宽度能够正常变化。
好像只能通过模拟input事件的方式来解决这个问题。

<template>
  <n-space vertical>
    <n-input v-model:value="value" type="text" placeholder="Basic Input" autosize/>
    <n-input
      v-model:value="value"
      type="textarea"
      placeholder="Basic Textarea"
    />
  </n-space>
</template>

<script setup lang="ts">
import { ref } from 'vue'

const value = ref(null)
</script>

Steps to reproduce

在 demo 中的 textarea 中输入字符串，input宽度不会变。在input中输入字符串，宽度能正常变化
