New behavior as of 1.21.121:
When using a controller, then pressing the chat or command key on a keyboard, you then cannot type anything at all. Popup keyboard flashes on and off. Also, when trying to type in a Sign, as soon as you press a letter it kicks you out of the Sign editor.
Affects 1.21.113 too. Whenever I use my keyboard to type a command, the on-screen keyboard pops in and out not allowing me the press Enter.
Also, when trying to type in any command, the keyboard pops up and you can’t see what you’re typing because it’s in the way.
Affects 1.21.121 too.
