Error message reading an HTML file after using rdflib::rdf_query()

Coming here via eblondel/zen4R#141 cc @oggioniale
rdflib::rdf_query() somehow influences a later call to xml2::read_html(), see below (in a clean session). Not using {reprex} because otherwise the message isn't in the output.

librdf error - HTML parser error: Tag nav invalid
{html_document}
<html>
[1] <body><nav>bla</nav></body>So "librdf error - HTML parser error: Tag nav invalid" is the surprising part.
Probably a redland problem ropensci/redland-bindings#99
