Component does not re-render after changing prop

[nekosaur]

Describe the bug

Updating bar prop of Foo component in App.vue does not trigger a re-render. Although the console shows [vite] /src/App.vue template updated.

If the template in App.vue is changed to

<template>
  <foo bar="baz" />
</template>

then everything works fine.
