Steps to reproduce

i was stumbling on problems with certain stuff not getting updated to new values after hydration using pregenerated sites with Nuxt 3. (see issue with reproduction here: nuxt/nuxt#22784)

after looking at it, Daniel concluded, it was a a vue-related problem, visible in the reproduction provided in this here issue. here is the code:

<script setup>
import { ref, computed } from 'vue';
const timestamp = ref();
timestamp.value = Date.now();
const imgSrc = computed(
  () => `https://dummyimage.com/600x400/000/fff&text=${timestamp.value}`
);
</script>

<template>
  <div>
    These values should all be equal:<br />
    {{ timestamp }}
    <div v-html="timestamp" />
    <img :src="imgSrc" />
  </div>
</template>

What is expected?

That the contents of the img src attribute and v-html get updated with the new value of the timestamp ref after hydration.

What is actually happening?

The server-generated img src attribute and v-html stay the same - not getting updated to the new value.
