Environment

I confirm that it happens on Edge and Chrome. Removed the MVC Wrappers as it happens with Kendo UI, too: https://demos.telerik.com/kendo-ui/pdfviewer/index

FireFox is working nicely. After all, the Mozilla Team is behind the development of PDF.js which is used in the PdfViewer component. Thus, this issue is probably tied to the capabilities of pdf.js within Chromium based browsers. It won't be surprising if this turns out to be a limitation.

Something similar is being discussed here, but it could be something different: https://github.com/mozilla/pdf.js/issues/6463
