IE11 Error using PDFViewer (with Polyfills)

Question

I have a Blazor App - everything works in Edge but not IE11 - I have added the polyfills

Using the SfPdfViewerServer control to display a PDF

IE Cocsole reports:

SCRIPT16389: Unspecified error.

pdfviewer-938a3e.min.js(1, 1314622)

IE11 Debugger points to pdfviewer-938a3e.min.js(1, 1314622) - which contains:

{return t.getBoundingClientRect().height},

Everything above this control on the page loads (some text, couple links - the links work), but the PDF viewer control does not load

Other Blazor Controls work (I tried the Calendar on another page and that loads fine)
