Selecting address with Enter key submits form

When searching for an address, if you use the keyboard arrow keys to scroll down the list to the correct address and then hit Enter to select it, it seems to try to submit the checkout form and highlights the form fields that haven’t been completed. In Chrome/Win10 it even scrolls down to the bottom of the page so the user doesn’t see the rest of the form they need to complete.

It all works fine if you select the address with a mouse click, it’s only if you hit the Enter key.

Any solutions?
