Got @undefined in Vue3

Hi, I tried to add this on our project using Nuxt3.

`"vue-mention": "^2.0.0-alpha.3"` and `"floating-vue": "^2.0.0-beta.24",`

When I select a suggestion from the popover, it becomes @undefined.

here's my code

```

import { Mentionable } from 'vue-mention'
import 'floating-vue/dist/style.css'

const props = defineProps({
taskId: {
type: Number,
required: true,
},
taskMembers: {
type: Array,
required: true,
},
user: {
type: Object,
required: true,
},
})

const message = ref('')
const members = ref(props.taskMembers)

@{{ item.name }}

```
