Running on localhost, this displays "Tag Name: CXX-FUNCTION; Instance of CxxFunctionElement: false", but when copied to jsbin, it shows "Tag Name: CXX-FUNCTION; Instance of CxxFunctionElement: true". I believe 'true' is the expected result.

Notes on HTML inadequacies

I'm the editor for the C++ Library Fundamentals TS, and I keep running into missing features in various bits of the HTML ecosystem that make this more difficult than it should be. I'm starting this document to record these so I can file useful bugs in the future.
