v-scroll-to breaks HTML5 form validation with Enter

Problem

If a HTML form has a button with v-scroll-to, that breaks form validation which occurs when a user presses Enter.

Steps to reproduce

1. Open jsfiddle at https://jsfiddle.net/semenov/ukt84qvy/7/
2. Type something in input 1, press Enter. The form validation for input 2 will NOT kick in, instead the page will be scrolled to a seemingly random (?) location:

3. Edit jsfiddle, remove v-scroll-to, re-run it.
4. Type something in input 1, press Enter. The form validation for input 2 WILL kick in, and the page will be scrolled to show input 2:

Expected behavior

Regardless of v-scroll-to, pressing Enter in a form scrolls to the input element that doesn't pass validation.
