Issues using library that uses react-transition-group/Transition

[miguelespinoza]

I'm having compatibility issues with https://github.com/fkhadra/react-toastify which uses react-transition-group

Here's an example of what I'm trying to accomplish:
https://codesandbox.io/s/jzp1p30j0y

• Create notification cards
• Try to dismiss with close button
• When attempting to remove I get this error:

Works fine with React equivalent: https://codesandbox.io/s/93w3z0p7y4

I've attempted to use this library (https://github.com/developit/preact-transition-group) as an alias but it's not compatible with v2 of react-transition-group

Thoughts if anyone has had issues with this before.
