strictTemplates option works only bound props

[revyh]

I tried vueCompilerOptions.strictTemplates and it works only on bound props.

// CustomButton.vue
<script setup lang="ts">

defineProps<{}>(); 

</script>

// AnotherComponent.vue
<template>
  <!-- this reports errors -->
  <custom-button :non-existent-props="'some value'" />

  <!-- this is not -->
  <custom-button non-existent-prop="some value" />
</template>

I expected volar to report in both cases because it doesn't matter how values are passed to props. The only thing that matter is whether the prop exists or not.
