Quassel IRC

Normally when I use the scrollbar or mousewheel to scroll up the chat window when it is already at the top of the loaded logs, Quassel client will load some backlog from the core. However, when a chat window is empty, this will not work. I have to make some text display in the chat window, e.g. using /topic, in order to retrieve more backlog.

1. Run quassel with separate client and core, and in client Settings/Misc/Backlog, set Additional Messages: 0.
2. Enter a usually quiet channel and accumulate some lines of chat.
3. Exit and reopen the client.
4. Select the channel in step 2, and before any message is displayed in the channel window, use mouse wheel to scroll up
5. No backlog is loaded. The expected behavior is to load the backlog from step 2.
6. Enter /topic, and scroll up using mouse wheel, the backlog is loaded.
