我尝试使用tiptap作为子组件，并将其内容传递给父组件的v-model，但tiptap的documentation似乎只提供了如何在没有script setup的情况下完成此操作的信息，script setup使用不同的API。
这是我的parent组件：

<template>
    <cms-custom-editor v-model:modelValue="state.content"/>
    <p>{{state.content}}</p>
</template>

<script setup>
import CmsCustomEditor from '../../components/backend/cms-custom-editor.vue'
import {reactive} from "vue";

const state = reactive({
    content: '<p>A Vue.js wrapper component for tiptap to use <code>v-model</code>.</p>',
})

</script>

这是child分量和tiptap：

<template>
  <div id="cms-custom-editor" class="cms-custom-editor">
    <editor-content :editor="editor"/>
  </div>
</template>

<script setup>
import {useEditor, EditorContent} from '@tiptap/vue-3'
import StarterKit from '@tiptap/starter-kit'

const props = defineProps({
    modelValue: {
        type: String,
        default: ''
    }
})

const emit = defineEmits(['update:modelValue'])

const editor = useEditor({
    extensions: [StarterKit],
    content: props.modelValue,
    onUpdate: () => {
        emit('update:modelValue', editor.getHTML())
    }
})
</script>

只要我在编辑器字段中键入一些内容，下面的代码行就会失败：

emit('update:modelValue', editor.getHTML())

并抛出此错误：

Uncaught TypeError: editor.getHTML is not a function

我使用了文档中的方法（第5章）。v-model），就像我说的，它不是为script setup设计的。
