While using pdfjs in frameworks with SSR like Next.js or Gatsby there is an error while build phase
```ReferenceError: window is not defined```

The error occurs at line 563 in `ui_utils.js`

Looks like all changes needs is:
```diff
const animationStarted = new Promise(function (resolve) {
  if (
    typeof PDFJSDev !== "undefined" &&
-   PDFJSDev.test("LIB && TESTING") &&
+   PDFJSDev.test("LIB && TESTING") ||
    typeof window === "undefined"
  ) {
    // Prevent "ReferenceError: window is not defined" errors when running the
    // unit-tests in Node.js/Travis.
    setTimeout(resolve, 20);
    return;
  }
  window.requestAnimationFrame(resolve);
});
```

There is an issue in react-pdf: https://github.com/wojtekmaj/react-pdf/issues/657
const eventListeners = (this._listeners[eventName] ||= []);
    eventListeners.push({
      listener,
      external: options?.external === true,
      once: options?.once === true,
    });
  }
  /**
   * @ignore
   */
  _off(eventName, listener, options = null) {
    const eventListeners = this._listeners[eventName];
    if (!eventListeners) {
      return;
    }
    for (let i = 0, ii = eventListeners.length; i < ii; i++) {
      if (eventListeners[i].listener === listener) {
        eventListeners.splice(i, 1);
        return;
      }
    }
  }
}
function clamp(v, min, max) {
  return Math.min(Math.max(v, min), max);
}
class ProgressBar {
