Bug Description

Actual Behavior

A DatePicker component initialized with an undefined value prop should be acting in uncontrolled mode, e.g. changing the value prop on a subsequent render should cause no change

Instead it does cause a change, the formatted value displayed inside the text box is updated to the new value (even if an undefined value is given). This in turn makes it seems like the component is acting in controlled mode, however it is not as the internal state value has not been updated.

This is evident when a maxDate or minDate is set as those show errors based on the internal state value not whatever the prop is. In the above reproduction, the user selects a date, then we update the value prop and maxDate prop to something before the time the user selected. Based on what is shown in the text box to the user, this should be a valid date (it appears behind the maxDate value), but it is not compared to the internal date value (still whatever the user manually selected in the calendar)

Expected Behavior

I would expect the value in the text box to reflect the internal state when running in uncontrolled mode. This would make it far easier to realize the component is in an uncontrolled mode instead of half uncontrolled, half controlled
