Correct.

No, setting nodeValue on a textnode should simply set the text inside 
the text node.  Setting nodeValue on an element is a silent no-op. 
Setting nodeValue never creates a "new DOM text node child".

led you to think the above so it can be rewritten....

I agree it makes for a test, and maybe a good one, but it's certainly 
being handled correctly!

Oh, really?  How so?  Citation needed, etc.
