When manually scrolling the log output, and there's new game output, the scroll position is forcefully set to the end of the stream.

What I expected to happen was...:
that my current position was retained.

What actually happened was...:
the log scrolls down to the end where new data is appended

Steps to Reproduce:
1. Scroll the log to an arbitrary position
2. wait for new game data, for example a chat message
3. notice the log is forcefully reset to end
