OPERATIONAL DEFECT DATABASE

listIndexes on normal collections and the system.buckets collection include a 2dsphereIndexVersion field in the response for a 2dsphere index, but listIndexes on the timeseries view does not. This block seems to be the culprit, because the index version field is on the top-level index spec object and not the originalSpec sub-object.
