When updating the grp-frontend mapbox-gl and react-mapboxgl-js I'm getting this error
Uncaught ReferenceError: _createClass is not defined
The errors seem to be arising since the JavaScript bundle is incompatible with some Babel transforms because of the way it shares code between the main thread and Web Worker. more info on this can be found here. I tried the solutions suggested on mapbox docs but didn't get it to work on Create react app. I've also tried solutions shared here to get V2 working.

1. Create react app configuration override Craco - https://github.com/gsoft-inc/craco This required major upgrades on react-scripts and other packages on grp-frontend which I feel would not be a good solution for other projects that would want to use this package.
2. worker-loader - Uncaught ReferenceError: _createClass is not defined (after transpiling with Babel) mapbox/mapbox-gl-js#10173 (comment). After installing this and adding it below imports I still couldn't get V2 to work.

Generally, It looks like the fixes will require customizing our bundlers. Since I didn't get a fix for V2, chose to Rollback the mapbox-gl version to the v1 which has no transpiling issues.

NB* We are still using V1 in reveal web
