add-on bug

I am new to Ember and am having issues with the {{#paper-select}} addon. I am trying to create a simple dropdown menu component, with six options in it it.

The component allows the user to scroll through the dropdown menu list. But it scrolls past the bottom of the list and goes back up to the top of the list.

I am wondering, how do I make it so the scrolling stops once it reaches the bottom of the list and does not go back up to the top? Similar to how if we scroll to the bottom of this page, it does not automatically go up to the top.

components/template.hbs
> {{#paper-select options=optionNames onChange=(action 'click') as |option|}}
> {{option.name}}
> {{/paper-select}}
