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
this._off(eventName, listener, {
      external: true,
      once: options?.once,
    });
  }
  dispatch(eventName) {
    const eventListeners = this._listeners[eventName];
    if (!eventListeners || eventListeners.length === 0) {
      if (
        (typeof PDFJSDev === "undefined" || PDFJSDev.test("MOZCENTRAL")) &&
        this._isInAutomation
      ) {
        const args = Array.prototype.slice.call(arguments, 1);
        dispatchDOMEvent(eventName, args);
      }
      return;
    }
    
    const args = Array.prototype.slice.call(arguments, 1);
    let externalListeners;
