Review comment:
Yes, the map is redone for each event purposely. It is only a map of the
attributes for the given event. The order of the events hasn't changed as a
result of this patch and is driven by the REST API response and has nothing to
do with the creation of this map. It works as intended.
Regarding your question SERVICEA and SERVICEB - both events are preserved.
