onInvalid event handler not passed to input. #119
Description
Expected Behavior
When marking the DatePicker as required it should also be possible to attach an onInvalid event handler to handle custom validation when a date is not selected.
Current Behavior
When marking a field as required, the browser default validation handler runs.
Possible Solution
Pass through event handlers to the underlying InputControl
Context
We are using the DatePicker component in a complex form where overriding the browser default invalid behaviour is an important UX consideration. As the <DatePicker /> component doesn't allow us to override the onInvalid handler, it makes the form seem janky and unprofessional.
