Target node environment when building with wrangler

I'm trying to use @mapbox/mapbox-sdk in my worker, however they have a browser entry point defined in their package.json which relies on window.XMLHttpRequest object being present, which causes the following error

[wrangler:err] ReferenceError: window is not defined
    at createRequestXhr (file:///<snip>/worker/node_modules/@mapbox/mapbox-sdk/lib/browser/browser-layer.js:105:13)
    at null.<anonymous> (file:///<snip>/worker/node_modules/@mapbox/mapbox-sdk/lib/browser/browser-layer.js:115:15)


Is it possible to either polyfill window.XMLHttpRequest, or target a node environment when bundling via wrangler?
