Problem/Motivation

This may be a bug in DomPDF, but I found a workaround in entity_print, so posting the issue for that and discussion.

When parsing a document, DomPDF is treating drupalSettings as a CSS property, debugging, this the end of the list of CSS properties it was processing:

border-style: solid none none none;
border: 2px inset;
display: block;
display: -dompdf-br;
display: -dompdf-image;
display: inline;
display: none; -dompdf-keep: yes;
"path":{"baseUrl":"\/","scriptPath":null,"pathPrefix":"","currentPath":"node","currentPathIsAdmin":false,"isFront":true,"currentLanguage":"en",             "currentQuery":{"":""

This results in an exception from the dompdf plugin, with errors like this:

Error generating document: Failed to generate PDF: '"path"' is not a valid CSS2 property., '"form_action_p_p"' is not a valid CSS2 property., '"uid"' is not a valid CSS2 property.

Proposed resolution

Log the exception, but don't prevent PDF generation, since the error doesn't actually stop anything from working.

Ideally the upstream css property parsing would distinguish between inline JSON and CSS styles better.
