I don't think the accessibility of this component is improved by making this arrow button focusable, since you can tab into the component and use the down arrow and Esc to open and close the suggestions list, respectively. Keeping it in the tab order means that users need to hit Tab an extra time to exit the component. I'd consider it an accessibility improvement if we remove it from tab order.
