[Feature]: Popover with overlay

[MickL]

Describe the feature

Hello!
It would be great to be able to give a popover an overlay like Dialog has. Currently it needs to be done manually:

...
<PopoverContent class="z-50">...</PopoverContent>
...

<AnimatePresence>
    <Motion
      :initial="{ opacity: 0 }"
      :animate="{ opacity: 1 }"
      :exit="{ opacity: 0 }"
    >
      <div
        v-if="store.isOpen"
        class="bg-black/20 fixed inset-0 z-10"
        @touchstart="isOpen = false"
      />
    </Motion>
</AnimatePresence>
