added check to focus spot on popup when key press

Issue
When the pointer is in use, spotlight focus can be lost from the Popup if the user engages 5 way. Even when the scrim is present.

Fix
Using PR https://github.com/enyojs/spotlight/pull/151 in Spotlight, when key press events are propagated on first spot the Contextual Popup will return Spotlight focus to it's own container.
