    windowPreview: Make St.Label use single line mode
    
    When a windowPreview is hovered or selected, it will show its window's
    title as a caption. That title may contain Newline characters which will
    effect the windowPreview size. Make the caption's St.Label use single
    line mode to prevent that.
