Steps to reproduce

I created my component using vnode h function from Vue. I passed this component to my toast notification. Everything seems to work, except that I cannot access any Vue context inside my component. I am getting this error:

Uncaught (in promise) TypeError: _ctx.$t is not a function
    at Proxy._sfc_render (AppNotification.vue:5:80)

App.vue

<template>
    <div @click="showNotification" style="cursor: pointer; font-size: 40px; font-weight: bold">
        {{ $t('click_me') }}
    </div>
</template>

<script setup lang="ts">
    import { h } from 'vue'
    import { toast } from 'vue3-toastify'
    import AppNotification from './components/AppNotification.vue'

    const showNotification = () => {
        const vnode = h(AppNotification)
        toast(vnode)
    }
</script>

AppNotification.vue

<template>
    <div>
        <!-- This throws an error: TypeError: _ctx.$t is not a function -->
        {{ $t('i_am_a_notification') }}
    </div>
</template>

What is expected?

I expected it to work.

What is actually happening?

It throws an error.

I don't think this is a core bug.
Maybe you should do it like below

toast(vnode,{
  $t: xxx
})
