Testfile here:

if (!this.appearance) {
      return Promise.resolve(new OperatorList());
    }
    const appearance = this.appearance;
    const data = this.data;
    const appearanceDict = appearance.dict;
    const resourcesPromise = this.loadResources([
      "ExtGState",
      "ColorSpace",
      "Pattern",
      "Shading",
      "XObject",
      "Font",
    ]);
    const bbox = appearanceDict.getArray("BBox") || [0, 0, 1, 1];
    const matrix = appearanceDict.getArray("Matrix") || [1, 0, 0, 1, 0, 0];
    const transform = getTransformMatrix(data.rect, bbox, matrix);
    return resourcesPromise.then(resources => {
      const opList = new OperatorList();
      opList.addOp(OPS.beginAnnotation, [
        data.id,
        data.rect,
        transform,
