@CompuIves I just got the same error when importing the latest d3 version: https://codesandbox.io/s/sparkling-glitter-lgz8n?file=/src/App.js`.

It seems to already be the case when you import from d3-zoom.

Is this a new error or was there potentially a regression?

Interesting, definitely seems like a new one. Going to do some testing on this today...
