All flow members are shown in IRC rooms, even if they are offline

For example, a flow that has 10 members, only 3 of which are currently online will show all 10 members in the IRC user list. However, in the web UI, only the 3 online members are shown unless you click the arrow.

This means that it's impossible to know who's actually online or not using IRC, and you have to keep checking the web UI for user status.

Or am I missing something?
