As we discussed, can you double check and then add a comment to the code
explalining how reporting works for the complicated push messaging /
notifications interaction?

Stefano and I are looking into this. It's a bit hard to distill the complexity
down into a meaningful comment here so I'm thinking we should land this CL and
file a bug for that issue?

Ok, has there been a bug filed for this? I didn't see one (sorry if I missed
it!).
