Description Ryosuke Niwa 2015-09-02 16:45:38 PDT 
http://w3c-test.org/dom/nodes/Node-textContent.html fails because we don't treat undefined as an empty string in textContent's setter.

As per https://heycam.github.io/webidl/#es-nullable-type, since the attribute is nullable, "if V is null or undefined, then return the IDL nullable type T? value null".

Our generated bindings missed the "or undefined" part. I believe there is even a FIXME comment about this in the bindings generator already.
