Current Behavior

If using transformations in the yup schema, i.e. .transform(), .trim() or similar, these transformations are not shown in the form managed by Formik.

Expected behavior

If using transformations in the yup schema, i.e. .transform(), .trim() or similar, these transformations should be reflected in the form managed by Formik.

Tested with recent Formik version.
