I think the reason here is that what the spec says is the right thing, and  
there probably isn't a Web compat reason not to do the right thing, but  
browsers haven't considered this to be high priority to fix.

Maybe we could remove the throwing from the spec, but it seems kind of sad  
to not catch this in the serializer.

Why would you drop the test?
