The pdf is not displayed using upstream pdf.js and the patch above aims to fix that.
Anyway something is still wrong when binding because of xml data in datasets without any namespace which should interpreted as xhtml.
So I think that before trying to bind we must know the type of the node in the template in order to guess that the value may be some xhtml.

This issue was fixed by:
Bug 1722768 - Update pdf.js to version 2.11.22 r=pdfjs-reviewers,marco
Differential Revision: https://phabricator.services.mozilla.com/D121125

But it created a worse rendering of another field: bug 1727377.
Please close this one as such. Thanks.

I can't verify this fix until its dependency is also verified.
