[Bug] unable to run with CRA

[martinjuhasz]

Description

I'm using CRA with react-app-rewired and somehow when deploying react-map-gl it fails to load the tiles.
The error i see is

An error occurred while parsing the WebWorker bundle. This is most likely due to improper transpilation by Babel; please see https://docs.mapbox.com/mapbox-gl-js/guides/install/#transpiling 4c2326de-1504-4cf4-913b-8260437c626e:1:37
ReferenceError: y is not defined

So it seems that CRA is transpiling mapbox-gl. If i read correctly here, react-map-gl should take care that his doesn't happen. I tried differnt things to exclude it, but without luck.

Any idea why this could happen? I have no imports of mapbox-gl directly in my code, only using react-map-gl.

Any help appreciated

Expected Behavior

mapbox-gl should not be transpiled when using create-react-app

Steps to Reproduce

I tried reproducing this behaviour in a sandbox, but that didn't work
