strictTemplates fails to report unknown components

[cexbrayat]

I think strictTemplates: true used to report unknown components used in a template (or am I mistaken?).

Using vue-tsc v1.8.10, the following component does not report any errors, even if <Hello> does not exist.

<script setup lang="ts">
import { ref } from 'vue'

const msg = ref('Hello World!')
</script>

<template>
  <Hello :msg="msg"></Hello>
</template>

Does it work in v1.8.9?

[cexbrayat]

I don't know, I had to disable strictTemplates for a while because of #3487

But I tried quickly in the stackblitz repro, and it doesn't look like it worked in v1.8.9

This problem is introduced in 376352a. It doesn't seemed to be related to #3487

@cexbrayat
Just discovered this issue myself, seems like my team has been without strict template type support for months.
I narrowed down the version.

This was working in 1.8.3 and then it does not work in 1.8.4

Do you know how to solve this?
or do you know if we can get someone to take a look at it?
