Could you add a TODO or comment related to the addition of the "no cover"
pragma? From your description in the CL it's a pretty serious problem and should
be documented.

Done.  It was just a small bug in the infrastructure code for the tests to
accept additional formattting names in the properties.  that might have even
already landed.  I will update the coverage asap in a follow on cl.
