Specifically, this part:

  The properties IDL attribute on HTML elements must return an
  HTMLPropertiesCollection rooted at the Document node

combined with the fact that all the properties are in the element's home subtree would mean that elements that are not in the document should always have an empty .properties.

That doesn't seem to be terribly useful, and as far as I can tell Opera doesn't implement that.  Neither does the upcoming Gecko implementation.

See upcoming testcase: it would alert 0, then 2, if the spec was actually followed here.  In Opera it alerts 1, then 2.
