Steps to reproduce the problem:
1. Create a form and add a date input as its only child element.
2. Focus the date input
3. Press Enter

What is the expected behavior?
The form is submitted / submit event is fired (implicit submission)

What went wrong?
Nothing happens.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No 

Did this work before? N/A 

Does this work in other browsers? N/A 

Chrome version: 52.0.2743.82  Channel: stable
OS Version: 10.0
Flash Version: Shockwave Flash 22.0 r0

Since browsers are encouraged to implement implicit submission https://www.w3.org/TR/html5/forms.html#implicit-submission, I'd expect any input type to submit the form on Enter press.
I know that there is no requirement, but for the sake of consistency it should be implemented. At the moment, Chrome also doesn't have another function mapped to Enter in date inputs. The absence of this makes it difficult to create a form that does not have any submit buttons in a cross-browser way, as FF and others dont' have date pickers yet.

Edge actually opens / closes the date picker in this case, so the problem exists there too.
