I'll need to see how the code coverage ABI works, but it might be more than possible that code coverage for those lines are tracked but there's no way to display it. If that's the case, some IDE might someday be able to expand the templates inline and ho coverage, or alternatively aggregate this data and show coverage for an entire template (and maybe use pretty colored lines to do so if you ask nice). "someday" being the keyword.
