Thanks! I have another one for you 
When you focus on a field (text or multi-select) and blur it without typing, it will automatically do form validation (probably because it has a validate attribute on the <Field /> which is automatically triggered on user input). It looks a bit weird:
Technically, validate should test for invalid content, not required field validation. That is something you can leave for HTML5 form validation or in the onSubmit event handler on the AtlasKit <Form /> element.
It is weird to tell me I did something wrong when I did not actually do anything wrong (focus / blur a field on it’s own does not constitute invalid input). Only invalid content in the field or clicking on Next with an empty field should trigger the validation to fail.
