Steps to reproduce

1. git clone [email protected]:brc-dd/volar-template-key-bug.git
2. pnpm i
3. pnpm vue-tsc --noEmit

Pasting here for completeness:

<script setup lang="ts"></script>

<template>
  <template v-if="true" :key=""></template>
  <template v-if="true" :key="{}"></template>

  <div v-if="true" :key=""></div>
  <div v-if="true" :key="{}"></div>
</template>

What is expected?

Error on line 4, 5, 7, 8 of Foo.vue

What is actually happening?

Error is only on line 7, 8.

There should be an error on line 4 saying v-bind is missing expression.

There should be an error on line 5 saying Type '{}' is not assignable to type 'PropertyKey | undefined'.

Any additional comments?

Is it possible to show vue errors when running vue-tsc? They are currently shown only in the editor. (Line 7 in the above example.)
