Pager not compatible with jquery 3.4.1

The PDFViewer pager is working correctly with jquery 1.12.4 and 2.2.4.  However, with jquery 3.4.1, the pager is not working.

If the scroller's top is 0 (top of the first page), you'll be able to scroll to the page #2 normallly.  Unfortunately, any page change after the first one will bring you to an incorrect offset (returning to page #1 will remain on page #2, while moving to page #3 will bring you after the end of the page #3)
