downloaded automatically, as the plugin does not execute scripts – it only detects fully qualified URLs for downloading and replacement. In short, don't do this:
``` js
-const cdn = "https://polyfill.io"
-const url = `${cdn}/v3/polyfill.min.js`
+const host = "https://example.com"
+const path = `${host}/script.js`

Instead, always use fully qualified URLs:
