Say I'm typing a message to my opponent in the chat. I'm in the middle of typing and let's say something happens: it's my turn now, or an undo request is going through, or the game ends. I can keep on typing and nothing goes into the chat. In some cases text will continue to appear in the box as the screen is fading away but when the screen comes back, my text has been cut off.
I feel like nothing should ever take my cursor away from the chat no matter what.
