Expected Behaviour

Build without error when i have a vue 3 component using script setup syntax + style tag with scoped property

Actual Behaviour

When i try to build my design system with a component using script setup syntax and with a scoped style tag i get this error:

[!] (plugin rpt2) RollupError: src/components/testworld/TestWorld.vue?vue&type=script&setup=true&lang.ts:4:22 - error TS7006: Parameter 'n' implicitly has an 'any' type.

The error is gone when:

• I remove the scoped from style tag
• I use DefineComponent syntax (with this syntax i can use scoped)
• I setup tsconfig with strict: off ( not a solution )

To be very clear, those 2 following components will NOT generate any error during build time:

<template>
    <h1>
      {{ age }}
    </h1>
</template>

<script lang="ts">
import { PropType, defineComponent } from "vue";

export default defineComponent({
  props: {
    age: {
      type: Number as PropType<number>,
      required: true,
    },
  },
});
</script>

<style lang="scss" scoped>
@import "../../assets/scss/tailwind";
</style>

<template>
    <h1>
      {{ age }}
    </h1>
</template>

<script setup lang="ts">
import { PropType } from "vue";

defineProps({
  age: {
    type: Number as PropType<number>,
    required: true,
  },
});
</script>

<style lang="scss">
@import "../../assets/scss/tailwind";
</style>

And this is a component generating the error above:

<template>
    <h1>
      {{ age }}
    </h1>
</template>

<script setup lang="ts">
import { PropType } from "vue";

defineProps({
  age: {
    type: Number as PropType<number>,
    required: true,
  },
});
</script>

<style lang="scss" scoped>
@import "../../assets/scss/tailwind";
</style>

I do not think we can help you here.

• the plugin throwing the error seems to be rollup-plugin-typescript2, which is not part of the rollup organization
• but I have a strong suspicion that it might actually be an issue of the Vue SFC compiler, which is also not part of the rollup organization
