Slot props are not rendering as expected

[sureshjoshi]

I'm not sure if I'm doing this correctly, but here is my component:

  const describedby = writable();
  const { container } = render(
    html`
    <${DescriptionProvider} name={"test"} let:describedby=${describedby}>
      <div aria-describedby=${describedby}>
        <${Description}>I am a description</${Description}>
        <span>Contents</span>
      </div>
    </${DescriptionProvider}>`
  );

And the snapshot that generates has <div aria-describedby=[Object object]>, but if I'm using a standalone component, then it would render a string headlessui-description-1.

I've tried using a get on the store, but I think that's a greedy get, so it's blank.

Am I handling the slot props incorrectly?
