getLabelFont() not working as intended

[klaas]

The lazy initialization of the font is dependent on touchUpFlag and thus it's either .thin or .regular but not changing as it is intended.

    fileprivate func getLabelFont() -> UIFont {
        if labelFont != nil {
            return labelFont!
        }
        
        let width = bounds.width
        let height = bounds.height
        let radius = min(width, height) / 2
        return UIFont.systemFont(ofSize: radius * fontSizeRatio,
                                 weight: touchUpFlag ? UIFont.Weight.thin : UIFont.Weight.regular)
    }
