configureLinkAttribute 点击后无效

[xygkevin]

lab.configureLinkAttribute = { type, attributes, isSelected in var atts = attributes switch type { case privacyType, agreementType: atts[NSAttributedString.Key.font] = isSelected ? kxFontMedium(12) : kxFont(12) default: break } return atts } isSelected == true时设置为粗体字， isSelected == false时设置为常规体， 但是点击之后就全部变成常规体了，粗体设置无效
