    Display PDFs from non-HTTP/HTTPS protocols
    
    We forced PDFs loaded via POST requests to become downloads to solve
    issue #1505, but forgot that PDFs can also be opened via other URI
    schemes. We shouldn't crash in this case. These can safely be loaded via
    PDF.js.
    
    Fixes #1611
