I click on Kickoff button in panel (left bottom side of screen) and immediately starts typing search phrase. Sometimes it shows me not the search result, but only static Favorites app list. I see that this happens if mouse was hovered to Favorites tab when I start typing search phrase. But this happens very often, because mouse move back from corner. This is not critical, but annoying. So will be good to fix this.
