Does PubSub API support multiple record crud operations for custom channels?

[ValeriyRCG]

I am subscribing to a custom channel with channel members of AccountChangeEvent and another custom object. I receive the events just fine when I update one of each record, but if I do any CRUD operations on more than one type of object (say I update 2 account records) then I never receive the event.

I experimented with the custom channel and cometd in java and it seemed to receive all the events.

I replicated this issue with the pubsub api java and javascript implementations provided by salesforce and I am unable to receive events from custom channels when updating two or more accounts.

Are there issues with these implementations or are they are done correctly and the pubsub api just does not support multiple record operations for custom channels?
