This can be reproduced on your demo page. If you inspect the input element there, you'll see this:
I would expect this element to only have the role="datepicker" and not the role="combobox". This caused an issue for us, because we use this attribute to check some things in our javascript code.
Hi Ferry v.d. Graaf,
This is not a bug but rather purposely implemented to be so. The role attribute of the DatePicker is combobox as this is the closest role attribute as per WAI-ARIA to the datepicker role. The WAI-ARIA accessibility specification does not expose a datepicker role.
You can use the data-role attribute that is of type datepicker to reference the datepicker input.
Hope this clarifies the situation.

Nikolay
