dev-tools/babel-plugin-prod causes errors with latest version (1.10.17)

[Oussama Mubarak]

When using interact.js v1.10.17 with babel and webpack, all seems to work fine in development, but errors occur in production due to the use of the "dev-tools/babel-plugin-prod" babel plugin.

I can't reproduce this in online tools such as JSFilddle, so I'm attaching a reproduction example:
interactjs-test.zip

To make it easier to see the errors, the reproduction adds the "dev-tools/babel-plugin-prod" plugin in development mode.

Expected behavior

No errors occur and dragging works.

Actual behavior

Errors occur and no interaction is possible.
Since this only happens in production, errors messages are not very helpful, but here are stack traces anyway:

In Firefox:

Uncaught TypeError: r is null

In Chrome:

It sort of seems like domObjects is not initialized.

I just tested with older versions, and this issue seems to go back to version 1.10.15. It is not present in 1.10.14.

I'm having the same issue with the babel plugin.
