On an Upload component, when Auto=”false”, it shows a broken image for PDFs and other file types.

To reproduce:  
On your Upload demo, upload a PDF on the “Trigger upload from code” example:

>
> The Blazor Upload component uploads single or multiple files to a server endpoint, with progress, validation, and custom headers.
