Feature request: Add support for missed messages

[daria-github]

Is your feature request related to a problem?

Currently we’re querying the network for all new messages that come after the latest message, but when a stream is offline and reactivates, it doesn’t pick up those messages for the inactive state.

Describe the solution to the problem

One approach is to detect when a tab has been deactivated, like a timestamp in local storage, and fetch the messages starting from there.

Describe the uses cases for the feature

Example here is bots that have large quantities of messages and are inevitably going to hit an offline state.
