The problem may be that the document doesn’t have a URI, so it is unable
to resolve the relative URI “#TMTRIANGLE”, even though it should be in
the same document.

How are you creating the SVGDocument?  You could try calling
setDocumentURI() on it (after casting it to SVGOMDocument) to give it a
URI of some sort.  If the document needs to be able to have relative
reference to files on the local file system, give it a URI like
"file:///some/where/file.svg"; then it will be able to resolve relative
URIs to files in the /some/where directory.  Or, if you don’t need to
reference local files relatively, even something like
"http://example.com/" should do.

Do that setDocumentURI() call just after you have built the document and
before you have installed it in the JSVGCanvas.
