This is a crucial issue for Survey123. In survey123 web app, all the question's runtime value is stored in a internal object(Model), if the date picker value(UI) changed, we sync the value to the internal object(Model), if the value in the internal object(Model) changed, we updated the date picker(UI), so the calciteDatePickerChange event should reflect all the value change for us.

1. For a required date question, we are not able to prevent submission when the input value gets cleared.
2. When the value gets cleared, we are not able to change the actual submission value since we don't know the value has been changed.
