I'm trying to write a userscript using TamperMonkey on Chrome.

I want to use https://github.com/Fil/d3-geo-voronoi so I put this in my script header:

// @require        https://cdn.jsdelivr.net/npm/d3@7.0.0/dist/d3.min.js
// @require        https://cdn.jsdelivr.net/npm/d3-delaunay@6.0.2/dist/d3-delaunay.min.js
// @require        https://cdn.jsdelivr.net/npm/d3-geo-voronoi@1.6.0/dist/d3-geo-voronoi.min.js

d3 and d3-delaunay are imported correctly but for some reason, d3-geo-voronoi is not. I can see in the chrome dev tools sources tab that tampermonkey has included all three scripts but the Chrome dev tools console shows that d3 and d3.Delaunay are defined but d3.geoVoronoi is not.

If I copy and paste the contents of https://cdn.jsdelivr.net/npm/d3-geo-voronoi@1.6.0/dist/d3-geo-voronoi.min.js into the console, d3.geoVoronoi is defined and works as I would expect.

Any idea what I'm doing wrong?
