v-close-popper doesn't seem to be working on v4

[alvarosabu]

Hi, I'm testing the v-tooltip@vue3 v4.0.0-alpha.1 following the migration guide here

  <VDropdown
    :triggers="['hover', 'focus']"
    boundary="body"
    :popper-options="{ preventOverflow: true }"
  >
    <a>Awiwi</a>

    <template #popper>
     I'm a popover
      <button v-close-popper>X</button>
    </template>
  </VDropdown>

I don't know if I'm applying the v-close-popper directive correctly, but doesn't seems to work.

I can't reproduce on my own on the current vue3 branch.
