Input history doesn't scroll to top after new message sent

Steps

1. Connect to core
2. Send enough messages that input history begins scrolling
3. Open input history, scroll to top
4. Send another message
5. Open input history

Expected

Input history scrolls to top, showing most recent message.

Actual

Input history remains at the former position. This can cause confusion if the previous message aligns with the top edge, as there won't appear to be more at the top if the fading scrollbar is missed.
