Steps to reproduce

Volar is enabled
Editor: VSCode

In the App.vue you can see the problem.

What is expected?

In App.vue i expect the following:

• IDE recognises MyTable as component (highlight it).
• IDE provides autocompletion for MyTable slots.
• IDE correctly infer scoped slots props types from MyTable.vue definition.

What is actually happening?

• VSCode does not recognises MyTable as component at all (it does not highlight it).
• There is no autocompletion for MyTable slots.
• All scoped slot props marked as any type.

Any additional comments?

Reproduction was made in SFC Playground, but you can't reproduce bug there.
Reproduction is very simple (only 2 components) so you can bring it to newly created project (npm init vue@latest).

There's a couple issues on the typescript

Here's running on the latest version of vue (3.3.4)

Some changes to the files:

<template>
  <div>
    <div v-for="item of data">
      <slot
        v-for="(_, key) in item"
        :name="`${String(key)}-cell`"
        :item="item"
      />
    </div>
  </div>
</template>

<script setup lang="ts" generic=" DataItem extends Record<string, any>">
defineProps<{
  data: DataItem[];
}>();

defineSlots<{
  [K in keyof DataItem as `${K & string}-cell`]: (props: {
    item: DataItem;
  }) => any;
}>();
</script>

@pikax Do you have any idea on this issue: vuejs/language-tools#3141 (comment)
