The problem is the messages can arrive to the constellation out of order. The constellation passes then on to browser.html, which I believe just reports the first one. We could try to be cleverer than that and batch them up, and wait before reporting. Or, as Manish suggested, we could filter out channel errors, and hope that any channel error will have some other error that gets reported.
