delete this[$extra];
      }
      return HTMLResult.FAILURE;
    }
    let marginH = 0;
    let marginV = 0;
    if (this.margin) {
      marginH = this.margin.leftInset + this.margin.rightInset;
      marginV = this.margin.topInset + this.margin.bottomInset;
    }
    const width = Math.max(this[$extra].width + marginH, this.w || 0);
    const height = Math.max(this[$extra].height + marginV, this.h || 0);
    const bbox = [this.x, this.y, width, height];
    if (this.w === "") {
      style.width = measureToString(width);
    }
    if (this.h === "") {
      style.height = measureToString(height);
    }
    const html = {
      name: "div",
      attributes,
      children,
    };
    applyAssist(this, attributes);
    delete this[$extra];
    return HTMLResult.success(createWrapper(this, html), bbox);
  }
