What do you want and why?

If a user has a react-final-form with a JS Set (or Map) in the initial values, the form resets on some activities, e.g. switching to another tab.

Possible implementation(s)

This can be fixed by using the initialValuesEqual prop:

import deepEqual from "fast-deep-equal"

    <FinalForm
      initialValues={initialValues}
      initialValues
