Currently, multiple fields ui for input type=date and type=month makes some fields read-only when possible value is limited by min/max attributes. However, we should not make all the fields read-only even if min and max is the same. For example, initial value of <input type="date" min="2013-01-09" max="2013-01-09"> is empty, but UI shows 2013-01-09 and user cannot change its value because all the fields are read-only. User should be able to set/clear value from UI in such case.
