print pdf files with correct document title

[mkofahl]

When printing pdf files using the integrated files_pdfviewer app, all print jobs will be titled "PDF.js viewer". This may have its origin in here: https://github.com/nextcloud/files_pdfviewer/blob/c992b55da9343e412f98e163a5066edcf6bdf37c/templates/viewer.php#L37

Is it possible to use the filename or document title instead? This would make it easier to identify print jobs.
