Why don't Clipper documents show-up in drafts in sidebar?

It’s was a bit hard to find the clipped documents - can only look up “all” or “top level…”
But when I found them I see they actually have a “draft” status, so theoretically should show up under “drafts” in sidebar - perfect place IMO - from there I can drag them anywhere. They don’t however.
But, if I do “untag as document” and then “tag as document” again - it appears there. Looks like a bug to me… Or do I miss something? What does a draft need to show up in sidebar?
