After clicking “Show more” in the @d3/d3-geo collection the target page (d3-geo / D3 | Observable) reports:
This collection is empty, so far!
Two bugs seem to be involved:
- “Show more” is displayed despite no further notebooks being available. To be honest I have no idea how the “before” argument works for collections.
- Having a before argument that undercuts the valid range reports the whole collection as empty, even though this only applies to the current filter.
