Vue 3 – renders non-element root node that cannot be animated

No.

<template>
  <div></div>
  <div>~someone~</div>
</template>

Yes.

<template>
  <div>
  　　<div></div>
    ~someone~
  </div>
</template>

If you do not use a “div” tag just inside the “Template” tag, you will get the same error. (By the way, it was possible to use other than div tags)
