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

constructor(attributes) {
    super(TEMPLATE_NS_ID, "arc",  true);
    this.circular = getInteger({
      data: attributes.circular,
      defaultValue: 0,
      validate: x => x === 1,
    });
    this.hand = getStringOption(attributes.hand, ["even", "left", "right"]);
    this.id = attributes.id || "";
    this.startAngle = getFloat({
      data: attributes.startAngle,
      defaultValue: 0,
      validate: x => true,
    });
    this.sweepAngle = getFloat({
      data: attributes.sweepAngle,
      defaultValue: 360,
      validate: x => true,
    });
    this.use = attributes.use || "";
    this.usehref = attributes.usehref || "";
    this.edge = null;
    this.fill = null;
  }
