E4X issue: elem.nodeName.toUpperCase is undefined

[joern]

jQuery's nodeName function doesn't quite work with E4X elements, eg. this causes an exception (see below):

$("body").append(<h3>Hi!</h3>);

The offending line is this:

return elem.nodeName && elem.nodeName.toUpperCase() == name.toUpperCase();

Seems like elem.nodeName what jQuery expects, therefore toUpperCase is undefined.
