How do I disable the message log in UE Editor?

Drag the tab in to main windows so it becomes part of it, that might help

Right now, I’m running into the bug UE-72811 (Unreal Engine Issues and Bug Tracker (UE-72811)) because I’m dynamically loading instances of the same level with a terrain. The bug wouldn’t be a problem if it weren’t for the fact it’s causing my PIE window to lose focus to the message log, and I can’t regain it. Unfortunately, I have a couple of engine plugins I use that aren’t compatible with 4.23 yet; so, upgrading is out of the question. Any suggestions on how to work around this?

All that does is put focus on the message log. It still takes me out of PIE.
