It would be worth checking if the remedial behavior exhibited by 
browsers is actually codified as part of HTML5's algorithm for 
constructing the DOM (I doubt it though). If so, this moves from being a 
"bug" to being documented standard behavior, which should then also work 
in future.

This is not the case here, though. The technique in question shows the 
correct code that would pass W3C validation.

And just to echo what Andrew said: techniques are only informative, so 
talking about whether or not a technique should be failed does not make 
sense. You pass/fail based on the more tech-agnostic success criterion, 
not based on techniques.
