Firefox/Chrome, latest version
- Operating system and its version:
Linux,Windows,mac
- PDF.js version:
v2.12.313
- Is a browser extension:
no

Steps to reproduce the problem:
1. create a custom viewer with 
```
async function getViewer() {
const viewer = await import(/* webpackChunkName: 'pdfviewer' */ 'pdfjs-dist/web/pdf_viewer');
const eventBus = new viewer.EventBus();
return viewer.PDFSinglePageViewer({
        container,
        eventBus,
        useOnlyCssZoom: USE_ONLY_CSS_ZOOM,
        // We can enable text/annotations layers, if needed
        textLayerFactory: new viewer.DefaultTextLayerFactory(),
        annotationLayerFactory: new viewer.DefaultAnnotationLayerFactory(),
        // textLayerMode: TextLayerMode.ENABLE,
        // currently the SVG renderer is not supported
        // and it has problems with telekom documents
        // so it will be disabled until it is feature complete
        // renderer: 'svg'
    });
}
```
2. console prints an error:
```
Unable to get page for page view TypeError: this.linkService._cachedPageNumber is not a function
    ensurePdfPageLoaded_fn base_viewer.js:1502
```
    
Looks like the problem is `IPDFLinkService` which is actually using the default one `this.linkService = options.linkService || new SimpleLinkService();` which does not have this function. of course we can use `PDFLinkService` which will probably work.

if (this._scrollMode === ScrollMode.PAGE) {
      if (pageNumber) {
        
        this._setCurrentPageNumber(pageNumber);
      }
      this.#ensurePageViewVisible();
      
      
      this.update();
    }
    if (!pageSpot && !this.isInPresentationMode) {
      const left = pageDiv.offsetLeft + pageDiv.clientLeft;
      const right = left + pageDiv.clientWidth;
      const { scrollLeft, clientWidth } = this.container;
      if (
        this._scrollMode === ScrollMode.HORIZONTAL ||
        left < scrollLeft ||
        right > scrollLeft + clientWidth
      ) {
        pageSpot = { left: 0, top: 0 };
      }
    }
    scrollIntoView(pageDiv, pageSpot);
  }
