Current behavior

Now InputMask is not possible to be used in calendar input.

Expected behavior

Will be great if calendar will have option that will allow to use InputMask based on the dateFormat option.

What is the motivation / use case for changing the behavior?

That feature will improve user experience when he inputs data from the keyboard.
