Steps to reproduce the problem:
1. Look at the bottom of page 2

style.letterSpacing = measureToString(this.letterSpacing);
    if (this.lineThrough !== 0) {
      style.textDecoration = "line-through";
      if (this.lineThrough === 2) {
        style.textDecorationStyle = "double";
      }
    }
    
    if (this.overline !== 0) {
      style.textDecoration = "overline";
      if (this.overline === 2) {
        style.textDecorationStyle = "double";
      }
    }
    
    style.fontStyle = this.posture;
    style.fontSize = measureToString(0.99 * this.size);
    setFontFamily(this, this, this[$globalData].fontFinder, style);
    if (this.underline !== 0) {
      style.textDecoration = "underline";
      if (this.underline === 2) {
        style.textDecorationStyle = "double";
      }
    }
    
    style.fontWeight = this.weight;
    return style;
  }
}
