What does this show if there are no expected outputs?  I would prefer if the TD
doesn't draw if there are none, or, if you want it to always draw, put it in the
more details section.

The more details section is currently broken
https://bugs.chromium.org/p/chromium/issues/detail?id=661146, so if you wouldn't
mind looking into why it's broken (I think it should be a trivial fix), I would
appreciate it.

Done.
