Error: only one instance of babel-polyfill is allowed

🐛 bug report

Description of the problem

Cannot use joymap from a CodeSandbox React app, which seems to also import babel-polyfill. The issue does not reproduce in CodeSandbox Vanilla (Parcel) template.

Recommended solution is to not import babel-polyfill in library code: https://babeljs.io/docs/en/babel-polyfill/#details so I filed an issue to joymap: diegodoumecq/joymap#6

But maybe there's also a solution from the CodeSandbox side which could make using such libraries possible.

Closing. Looks like this was fixed somewhere, does not reproduce in the test sandbox https://codesandbox.io/s/3xlknpxpnq
