Current behavior:

1. Open a page with an ion-input field.
2. Tap on the input field to open keyboard
3. Press enter on keyboard
4. Page immediately transitions to the previous page (goes back).
5. Keyboard closes.
6. Form submit handler is not triggered.

Expected behavior:

Switching to the next field or submitting form if this was the last one. No action would also be preferable.

Steps to reproduce:

Follow current behavior on presumably any Ionic app with ion-input.

Related code:

None. Every sample app repo I created was completely ignored by Ionic team. Try it on your app's first.
