Report every failed fetch instead of discarding it

Twenty-four fetch chains ended in an empty catch, which is not error handling
but error deletion: the request fails, nothing renders, nothing is logged, and
the surface sits on Loading forever. That is how the mesh chat's ReferenceError
read as a slow load for as long as it did.
