I guess font lock is based on the outer block, which in this case doesn't
correspond to any major mode, so there is no font lock. Or at least no
major-mode-based font lock. Org markup such as for =code= *is* font locked.

One could argue that this isn't entirely consistent with the fact that
=org-edit-special= *does* recognise the inner code block. It certainly would be
nice if font lock did, as well.
