[GeoPath] Rendering issue with simplified topojson

[techniq]

Most prevalent with simplified paths, such as when using import { presimplify, simplify } from 'topojson-simplify';. REPL. Also visible on SketchyGlobe example (especially when you turn down the "Min area").

This d3 / svelte-canvas example does not have the issue (gist)

See discussion

[techniq]

This d3-only example has the same issue

[techniq]

Using worldTopoJson.objects.land instead of worldTopoJson.objects.countries displays it as a path/winding issue.

Also, I haven't been able to reproduce it on this d3 example example (need to set feature.attr("fill", "red");)
