After clicking “Show more” in the @d3/d3-geo collection the target page (https://observablehq.com/collection/@d3/d3-geo?before=2018-08-08T22:51:32.154Z) 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.
