How load html content into Quill wysiwyg editor? Vue 3

I want to use @vueup/vue-quill ^1.0.0-beta.7 on my control panel admin based on vue ^3.2.29.

Unfortunately, I noticed that loading HTML content is not working for me. Quill converts <div> tags to <p> tags for me, also removing classy and css styles, which destroys the appearance of the content. On backand i use Laravel.

Can anyone help me with this? I sit on it all day to no avail.

<template>
// [...]
 <QuillEditor
       ref="mainContent"
       v-model:content="form.content"
       style="min-height: 300px"
       :options="editorOptions"
       theme="snow"
       content-type="html"
       output="html"
       @text-change="countMainContent"
/>
