embedpdf failures in a self-contained page

This page is built with embed-resources: true, so each PDF is inside the page. No embed on it can show its PDF. The checks in tests/ open a copy of the page with no other file beside it.

A file that is not a PDF

The file files/broken.pdf holds text, not a PDF, so PDF.js cannot load it. The embed shows “This PDF cannot be shown here.” and a “Download the PDF” link that saves the file as broken.pdf.

Download PDF file.

Inlined PDFs that cannot be decoded

These two embeds are written by hand, not by the shortcode. Each data-src is a data: address whose base64 holds @, which is not a base64 character, so the browser cannot decode it. The first embed is set to renderer=pdfjs and the second to renderer=native. Each shows “This PDF cannot be shown here.” with no link.
