The page scrolls when you press 'space' on a single select input

[ollietreend]

Describe the bug

When a single select input is focussed and the 'space' bar is pressed, the page scrolls down.

To Reproduce
Steps to reproduce the behavior:

1. Go to the 'Single select input' section of the Choices.js demo
2. Use Tab key to navigate to & focus a single select input
3. Press Space key
4. The selected input scrolls out of view

Expected behavior
The single select input should have opened, without the viewport scrolling and without a Space character being entered into the input's search box. This is standard behaviour for select inputs when navigating with a keyboard.
