dataScope prop doesn't work with composition api

[iv-thomson]

When using dataScope prop with examples that use composition api OR do not have a script tag I get following error:

t2.data is not a function

Please, check the demo for more details:

Example used in demo:

<template>
    <h6>{{ new Date(test) }}</h6>
</template>

<script setup>
  const test = "10 Dec 2028"
</script>
