The new Wikipedia button doesn't get unselected if I update my search string so that there is a local result. This can happen if I originally mistyped the name of an application. It's easy to overlook that the Wikipedia button is selected and just hit enter intending to launch the application, but instead get the web page.

The selection goes back to the first result in the top section when results are updated in other sections.

E.g
1. Typing "app" gets the first application result selected
2. Updating the string to "appe" gets no application results, but gets Appearance Preferences selected under Preferences
3. Updating the string back to "app" gets the first application result selected again
4. Updating the string to "appeal" shows no local results and selects the Wikipedia button
5. Updating the string to "appea" shows Appearance Preferences result under Preferences, but keeps the Wikipedia button selected (wrong behavior)
