Current behavior:

If the first list item is selected (either month, day or year) this item is not rendered or written to the value.

Expected behavior:

Showing the selected date.

Steps to reproduce:

Select the first item e.g. Januar, 1, 2017
Close with "Done"
Nothing is rendered. Try selecting e.g. Januar, 2, 2016 ==> The "2, 2016" is displayed, but not the Januar.

I can also reproduce this issue with @ionic/[email protected] and the new docs (locally).
Related to #14563.

Thanks,
