Unable To Join Servers After Switching To Something Else In Fullscreen

I play and screen record record in fullscreen, and whenever I exit full screen to start recording, for whatever reason when I go back to Minecraft, it doesn't let me join servers until I restart the game. This was never an issue until this update.

How to replicate:
1. Open Minecraft in full screen.
2. Switch to something else.
3. Go back to Minecraft, and try to join a server.

If you don't experience the same issue, try this:
1. Open Minecraft in full screen
2. Switch to OBS and start recording
3. Go back to Minecraft and try to join a server.
