[v8] TypeScript error when extending setup helper

[Mikilll94]

I have the following component:

<template>
  <div>{{ text }}</div>
</template>

<script lang="ts">
import { ref } from "vue";
import { Vue, setup, mixins } from "vue-class-component";

const Super = setup(() => {
  const text = ref('A')

  return {
    text,
  }
})

export default class HelloWorld extends mixins(Super) {
}
</script>

It throws TypeScript error:

Here is the repro project:

setup doesn't generate constructor but you should use it for class properties.

It's "alternative approach" ...

It's "alternative approach" ...

So are you saying it's not implemented yet?
