Trying to use the "New" Rietveld UI, i.e. the one not deprecated.

Is filing bugs like this it or moot now that we're switching to Gerrit?

Anyway, sometimes comments are not showing up.

See this code review, patch set 2, comment on pdf/out_of_process_instance.cc:

With the old UI the comment shows up. With the new UI the comment doesn't show up so I can't reply to it.
