    mouse: Reset test area to the bottom at every try
    
    This prevents window resizes from making the first visit to the
    mouse test area one that doesn't scroll all the way to the bottom.
    
    1. Open System Settings
    2. Open a panel that's smaller than the mouse one (eg. Background)
    3. Back to overview
    4. Open Mouse panel, click on test button
