Description
The subunits layer for the USA map includes slivers of Canadian provinces (which is unintended).
Screenshots
Steps to reproduce
- Open /dist/topojson/usa_50m.json in Mapshaper
- Zoom in to the top of Washington state
- Note the sliver of British Columbia above Washington
Notes
- This issue stems from the fact that the world subunits layer (coming from NE data) is clipped using the shape of the USA from the UN
- These two shapes don't match exactly, so the slivers result from the clipping operation
- We should check the other subunits layers for a similar issue

"unintended" or giving the game away? :-)
