Contact form breaks One-Page Site skeleton

I'm trying to add a contact form to a one-page site created using Grav's One-Page Site skeleton. It works fine, except for one highly irritating detail: as soon as the comment form is added to the bottom of the page, browsers (Chrome, Firefox, Konqueror) no longer open the page at the top, they jump somewhere to the middle of the page, without, however, targeting any particular anchor.

Here's the test site:

What am I doing wrong? Thanks for any suggestions!

Seems like the contact form has "autofocus" defined on the Name field, and the browser scrolls to that.

The autofocus-attribute really should be outlawed from virtually everywhere, it only works well when the page only contains a form, and this skips a step for user experience.

Turning the autofocus off did the trick. Thanks!
