Once you enter the world or server, you may not be able to input into the chat.

Steps to Reproduce:

1. Enter or open a world or join a server.
2. Open the chat and enter the command. A normal message might be fine. (may occur at this point)
3. Please open the chat again and try entering your message.

Observed Results:
You can no longer type messages, and Minecraft no longer accepts keyboard input when the chat screen is open. (Including Esc key)

Expected Results:
You can enter chat and close the screen.

Screenshots/Videos attached: (I tried to take a video, but it didn't happen this time.)

Notes:
・It seems like sometimes it happens and sometimes it doesn't.
