Yes, I agree: that second behavior is logical. I just emphasized it as,
consequently, we can't export anything (not even the results -- though, that
does not make much sense) to HTML, as exposed by the ECM.

The only buggy behavior is the first one: the fact that the "code" block
disappears, as you say.
