I am never able to reproduce this, but every once in a while I will click on the console and instead of selecting what I clicked on, the console will scroll to the top.
Created attachment 257897 [details] [Proposed] Patch I am not entirely sure why the focus call was necessary in LogContentView, but removing that call has stopped this from happening for me. With that having been said, I have no way of reproducing this issue, but I've been testing with it for a few days and haven't seen this issue at all.
