ACK.

Your logic is flawed. getElementsByClassName() was not invoked on an object
implementing the HTMLElement interface here; it was invoked on an object
implementing the (HTML)Document interface. That is a separate method, as
even your own references say.

So this example does not apply here in two respects:
1. another method
2. another selector

Again you have referred to a Working Draft and a Working Group Note, which
both are non-normative, although a Proposed Recommendation and a
Recommendation, respectively, are available.
<http://www.w3.org/TR/2014/PR-html5-20140916/infrastructure.html#common-dom-interfaces>
refers to
<http://www.w3.org/TR/dom/#document>
and thus
<http://www.w3.org/TR/dom/#dom-document-getelementsbyclassname>
and
<http://www.w3.org/TR/dom/#dom-parentnode-queryselectorall>
